Theresa May gets massive boost from voters over her Brexit plan as she opens up 17-point lead over Jeremy Corbyn after his disastrous re-launch

THERESA May is flying high off the back of her Brexit speech this week, with the latest polling showing the Conservatives opening up a 17-point lead over Labour.

Voters overwhelmingly back her plan for leaving the European Union, and 55% said it would be good news for Britain.

The first polling since she outlined her plans for Britain to leave the Single Market showed that the public were behind her plans by a margin of two to one.

The latest numbers from YouGov give the Conservatives a 17-point lead over Labour. The Tories have had a bounce and are currently on 42%, Labour on 25%, the Liberal Democrats on 11% and, Ukip on 12%.

This is one of the largest gaps the Tories have had over Labour since they took office in 2010 - last year they secured an 18-point lead in October.

And it looks as though Mrs May has passed her first Brexit test, as she told Sun readers exclusively today that she would make Brexit work for the workers.

Polling conducted on Tuesday and Wednesday this week showed that 47% of voters had confidence in her negotiating skills, and 48% agreed with her when she said that no deal  with the EU was better than a bad deal.

However, 56% of people did not think the EU would agree to the sort of deal the PM will be fighting for.

And a majority of people - 57% - supported the Prime Minister's calls for us leave the Single Market, which will leave us free to control our own borders.

Remain voters still thought we should stay in it, but were evenly split over the issue of the customs union. Mrs May was undecided over the customs union, and said it would be down to the Brexit talks.

Today the PM declared the UK was "open for business" despite Brexit as she addressed global financial chiefs and political leaders at Davos.

The polling leaves Jeremy Corbyn's Labour continuing to struggle after a disastrous relaunch last week.

Voters still remain confused with where the Opposition stand on immigration. Separate polling showed that 31% of people thought Labour wanted to relax the rules, and 19% thought the party wanted to keep them the same.

Just 13% thought they wanted to tighten the rules.

While Mr Corbyn has repeatedly said he is comfortable with the current levels of migration to the UK, other members of his party say that they should change their stance and back "managed migration".

Shadow Foreign Secretary Emily Thornberry said last weekend the party wouldn't "die in a ditch" to protect the freedom of movement principle.

Last week it was briefed that the Labour leader was prepared to change his tune and say that the party was "not wedded" to the idea.

But in a speech the next day he added "nor do we rule it out" - leaving voters confused about where they stand.
