SIR Keir Starmer is set to become Britain’s next Prime Minister after thumping Rishi Sunak with a projected landslide 170-seat majority.
The exit poll puts the Labour leader on course to thunder into Downing Street with 401 MPs compared to the Tories' 131.
It would see Labour's Commons haul increase by 209, while the routed Tories would plunge by 241 compared to the 2019 election.
The Lib Dems are forecast to swell their rump to 61, while Nigel Farage's Reform are on course for 13 seats in an earthquake result.
And the SNP are in for a bleak night with the exit poll culling them to just 10 seats at Westminster.
On a historic night:
- Exit polls predicted a huge Labour landslide of 410 seats
- Piers Morgan described it as a 'political and social earthquake'
- He told our Never Mind The Ballots election show that Sir Keir MUST deliver after the Tory disaster
- Nigel Farage was elected MP for Clacton on his eighth attempt at Parliament
- A battle for the soul of the Conservative party was already underway
- Defence Secretary Grant Shapps was defeated by Labour, while Justice Secretary Alex Chalk lost to the Lib Dems
- Other Cabinet Ministers including Jeremy Hunt and Penny Mordaunt were looking likely to lose their seats
- Mr Farage basked in record swings to his fledgling Reform party
- Lee Anderson won the party's first seat of the night in Ashfield
- Shadow education secretary Bridget Phillipson all-but claimed victory for Labour as she was elected
Speaking at his own count in the early hours of Friday, Sir Keir said: "People around the country have spoken... and they are ready for change."
It puts an end to 14 years of Tory rule after Mr Sunak’s early election gamble failed to revive the party’s flagging fortunes.
Sir Keir's predicted 170 majority is just shy of the 179 seats won by Tony Blair in 1997.

Barring a spectacular overnight upset, the PM will formally resign to King Charles on Friday morning before Sir Keir is asked by the monarch to form the next government.
He will then appoint his Cabinet before finalising a blizzard of new laws to be announced to Parliament on July 17.
Labour’s expected victory is a significant turnaround from five years ago when the party crashed to its worst defeat since 1935 under Mr Corbyn.
However polls have shown Sir Keir’s own personal appeal will be among the lowest of any incoming premier.
Tonight Sir Keir said: "To everyone who has campaigned for Labour in this election, to everyone who voted for us and put their trust in our changed Labour Party - thank you."
And Labour veteran Lord Peter Mandelson hailed the results as a "political meteor".
The final results are likely to show a collapse in Tory support in both the Red Wall seats won by Boris Johnson, as well as their traditional heartlands in the south.
Shortly after midnight, Labour gained the swing seat of Swindon South from the Conservatives with a 9,606 majority.
It sets the tone for a grim night for Mr Sunak who braced for sweeping losses across the country.
Reacting to the exit poll, former Tory leader Lord William Hague said: "If that is the result... that would of course be a catastrophic result in historic terms for the Conservative Party."
But in a glimmer of hope he said 131 seats is enough to "just about mount an effective opposition" against Labour.
Mr Sunak has been under further pressure from Mr Farage’s Reform party and Sir Ed Davey’s resurgent Lib Dems.
Mr Farage - who is on course to win in Clacton - said: "We’ll see what happens but if that’s the result that would be a massive first step for this - I’m going to call it a movement - a political party is only part of what we’re all about."
Analysis: Britain will awake to a political earthquake
By Kate Ferguson, Political Editor Sun on Sunday
BRITAIN will wake up tomorrow to a political earthquake.
If the exit poll is right, Labour have stormed to victory with their biggest majority in their 100 year history.
It is a jaw-dropping turnaround from the dark days of the Jeremy Corbyn era of 2019, when the party suffered their worst result in history.
The Tories look set to be decimated. The most successful political party in Europe has been reduced to just a rump of 131 MPs.
Be in no doubt - this is a nightmare for the Conservative Party. They now face the painful task of having to rebuild and choose a new leader.
But the big story of the night is Nigel Farage’s Reform party, who are expected to win a staggering 13 seats.
This political maverick has lobbed a grenade into Westminster - and he is only just getting started.
Reform is expected to win the key seat of Hartlepool - the Red Wall seat in Labour’s old heartlands which turned Tory under Boris Johnson.
Nigel, 60, the godfather of Brexit, is a charismatic leader well trained in waging war on ‘political elites’ from his days in the European Parliament.
He had run and failed to become an MP seven times before.
He has finally won on the eighth attempt - and looks set to have a dozen Reform MPs with him.
He has the potential to change the face of politics forever,
Sir Keir Starmer and the next leader of the Tories - whoever that may be - should brace themselves.
If successfully elected as an MP it will put an end to his seven-time losing streak to enter Parliament.
The first result of the night in Hougton and Sunderland South saw a 13.4 swing to Reform, who beat the Tories into second place.
The safe Labour seat saw incoming Education Secretary Bridget Phillipson become the first elected MP with 47.1 per cent of the vote.
She said: "Tonight the British people have spoken. And if the exit poll this evening is again a guide to results across our country, as it so often is, then after 14 years the British people have chosen change."
Mr Sunak’s failure to neutralise Mr Farage’s insurgents will kickstart Conservative bloodletting between moderates and right-wingers.
Minister Andrea Leadsom said tonight: "Perhaps we have not been Conservative enough."
Cabinet Ministers Jeremy Hunt, Grant Shapps and Penny Mordaunt are all expected to lose their seats.
Grassroots darling Kemi Badenoch is currently the bookies’ favourite to succeed him.
The Tories have been heavily criticised for running one of the most disastrous campaigns in the party’s history.
Exit polls: Everything you need to know
THE exit poll gives Brits a sniff of the election result just minutes after voting ends.
Interviewers at 133 polling stations across the country ask voters to fill in a replica ballot paper and put it in a ballot box as they leave.
The pollsters choose a mix of constituencies which best reflect national trends, many of which are marginal seats.
Data collected at polling stations is sent in a secure pipeline to a secret location in London where boffins crunch the numbers.
Their phones are taken away and the room is protected by security guards.
It has usually been on the money in recent years - except in 2015, when it predicted a hung parliament only for David Cameron to win a majority.
Number-crunchers also got the result wrong in the 2016 Brexit referendum, when the exit poll suggested Remain had won.
The faulty poll even prompted Brexiteer Nigel Farage to concede defeat on Twitter - before rejoicing at the Leave victory in the morning.
Expert Javier Sajuria told : "As polls go, it is probably one of the most reliable.
"Even in 2015, when the polling industry suffered a lot of criticism for their failures to anticipate a Tory majority, the exit poll outperformed everyone else.
"In general, I would say that the UK exit polls have been largely successful, and much better than in other countries."
Veteran BBC presenter David Dimbleby has revealed the exit poll to the nation following 11 different elections from 1979 to 2019.
Dimbleby said revealing the winner of the election can be a "heart-stopping moment".
But he caused a stir this week by saying the exit poll is "the worst invention ever".
Dimbleby told the BBC's Newscast podcast: "The exit poll is the bane of the broadcaster’s life.
"It’s the worst invention ever brought in - it’s like a thriller and you’re given the answer before we’ve even started on page one.
"The exit poll seems to me entirely detrimental to the excitement of election night.
"It gives people something to talk about until three in the morning when the first serious results flow starts.
"But I never liked them. It takes the fun away."
While winning a fifth election in a row is unprecedented, recriminations were last night underway in Tory high command over the misery of the past six weeks.
It included a string of unforced errors including returning early from the D-Day commemorations and the betting scandal.
It added to wider structural problems like funds drying up as donors closed their chequebooks.
And candidates were furious that various Cabinet Ministers had effectively conceded defeat on the airwaves ahead of Polling Day because it dispirited their activists.
Former Tory Chancellor George Osborne has said that the election result is the Conservative Party’s “Waterloo” moment - even though they didn’t do as badly as expected.
He said: “It’s going to sound odd there will be a bit of a sigh of relief even though its the worse result since 1832 when the Duke of Wellington was running the country - though this feels more like the Tory party’s Waterloo frankly.
“We are going to see a load of people lose their seats, household names, or at least those who follow politics, household names.
“It will be a huge mistake to take a lot of comfort from this but there were people thinking and the polls were suggesting it could be an extinction night for the Tory party, an extinction level event and the Tory party would never come back.
“I think there will be a lot of Conservatives saying we can come back.”
Mr Sunak did manage to land some blows on tax and immigration during a series of campaign debates.
Sir Keir has run a cautious campaign and unveiled a manifesto of “no surprises” that pledged not to raise the headline rates of national insurance, income tax or VAT.
Mr Sunak spent the majority of his time visiting seats with sizeable Conservative majorities, where even there he took a pummelling on the NHS, immigration and MP sleaze scandals blighting his clean personal image.

23:30 - First expected declaration in Blyth and Ashington, which are expected to be held by Labour

He is almost certain to resign as Tory leader one year and nine months on from succeeding Liz Truss.
But the outgoing PM may not resign immediately and could choose to stay put until party members pick his successor.
Alternatively, a “caretaker” such as Deputy PM Oliver Dowden, could temporarily take charge.
The Tory leadership contest could be immediate or delayed until later in the year, giving party elders time to reflect and consider next best moves.
But even as the election campaign was in full swing, Tory leadership hopefuls were secretly canvassing support.
The contest could get brutal as the moderate and hard right Tory tribes fight for the soul of the party.
Minister Steve Baker tonight appealed for an end to endless infighting, saying the constant "regicide" must be stopped.
Ex-Justice Secretary Sir Robert Buckland was the first Tory big beast to lose his seat as his Swindon South seat turned red.
The centrist politician kickstarted the looming civil war with a swipe at Conservative colleagues like Ms Braverman trying to drag the party to the right.
He said: "I'm fed up with personal ambition and jockeying for positions."
Business Secretary Ms Badenoch is the 4/1 frontrunner and expected to run on an anti-woke platform having led the campaign against trans infringement on women’s rights.
Ex Home Secretary Suella Braverman and Priti Patel as former Immigration Minister Robert Jenrick would offer hardline stances on borders.

One Nation Tories are desperate to battle from the centre, while from the right a core group of MPs want to take the fight to Mr Farage and Reform.
Previous elections: How the Tories gained and held power
By JACK ELSOM, Chief Political Correspondent
2019 - the Brexit election
BORIS Johnson called the 2019 general election to break the Commons deadlock over Brexit.
A coalition of Opposition parties and Tory Remainers were blocking his deal from passing and had effectively put the country in limbo.
After purging the Conservatives rebels - and battling Jeremy Corbyn to actually let him trigger the election - the date was set for December 12.
The winter campaign saw Johnson adopt an effective Get Brexit Done slogan while Labour struggled to explain their policy of holding a second referendum.
The result saw the collapse of Labour’s Red Wall fortress of northern seats who switched to back the Tories and helped them win an 80-seat landslide majority.

2017 - May fluffs it
THERESA May was riding high in the polls in the spring of 2017 when she decided on a walking weekend in Wales to call a snap election.
While commanding a slim majority, she wanted her own mandate having inherited No10 from David Cameron after a Tory coronation contest.
But the wheels quickly fell off her presidential-style campaign, resulting in a disastrous press conference where she infamously insisted “nothing has changed!” as her social care policy was ripped to shreds.
It cost her the Tory majority as Jeremy Corbyn performed better than expected, and May was forced to do a confidence and supply deal with the DUP.
CON: 317/42.3% LAB: 262/40%
2015 - Cameron wins majority
DAVID Cameron let his Tory-Lib Dem coalition reach its full five years, resulting in a long 2015 campaign.
He successfully turned on his own deputy PM Nick Clegg - blaming them for all the faults of their government and asking voters to help him cut them loose.
It was an effective strategy that saw him clinch a small Tory majority, the first since 1992.
CON: 330/36.1% LAB: 258/29%
2010 - Cameron falls short
AFTER 13 years of New Labour, Gordon Brown was ousted as Prime Minister - but the Tories fell short of an outright majority.
Brown had bottled calling an election in 2007 upon succeeding Blair after letting speculation run and run.
After five days of coalition talks, Cameron forged a deal with Nick Clegg's Lib Dems.
