that it was difficult to estimate the deaths in care homes among people transferred from hospital.
“There were lots of factors that could be involved in the high death toll: access to personal protective equipment, the difficulty of isolating infected patients within a care home environment, and staff working across multiple care homes,” she told The BMJ.
In another part of the expletive-filled messages the PM purportedly asks 'wtf do we do?' COVID TESTING Mr Cummings doubled down his attacks on the Health Secretary's handling of the testing rollout by accusing him of trying to soak up the credit for the 100,000 daily target.
He said Mr Hancock tried to rewrite history by pretending he had the “heroic” idea of ramping up testing to 100,000 a day.
He writes in his blog: "A public announcement was in principle definitely right but he did what he always did — he focused on the media and himself then lied.
"Testing, like vaccines, was removed from his control in May because of his incompetence and dishonesty March-April."
Health committee chair Jeremy Hunt tweeted: "There was more melodrama than normal but it is not possible to stack up the most sensational revelations without evidence.
"Dominic Cummings' tweets show the PM's total frustration ('f***ing useless' etc.) but do not prove anyone 'lied'."
Mr Cummings claimed the PM would regularly "whinge" to him and others about Mr Hancock but would never confront the latter directly.
In the most eye-catching exchange, the mastermind of the Brexit campaign who was at the heart of the Covid response until leaving No10 in November noted the US's rapid increase in testing capacity.
He criticised Mr Hancock, or "MH" as he referred to him in the message on March 3 last year, for apparently saying he was "sceptical" about meeting a new UK target having earlier said it would "definitely" be met.
The PM apparently responded: "Totally f***ing hopeless."
The PM lashed out at Mr Hancock, says Mr Cummings Ventilators Mr Johnson appeared to lay blame for the shortage of ventilators at the feet of the Health Secretary.
Messages between him and Mr Cummings on March 27 2020 fume against the lack of equipment, which ministers were scrambling to buy.
Mr Cummings said in a message to the PM: "They've totally f***ed up ventilators.
"I just heard officials admit we have been turning down ventilator offers because the price has been marked up."
They've 'totally f***ed up ventilators', the message shows The PM replied: "It’s Hancock. He has been hopeless."
Mr Cummings also recalled feeling utterly exasperated that officials decided to ship PPE rather than fly it in to save money - and said the lack of protective gear "killed" frontline staff in the first wave.
Mr Cummings wants Mr Hancock to be sacked Boris Johnson's exit plans Boris Johnson will step down after the next election to "make money and have fun" according to his rattled former aide.
The embittered aide also suggested the nation's Covid enquiry wouldn't start for "years" as it is "designed to punt the tricky parts until after this PM has gone."
Mr Johnson has announced a public inquiry into the Government's handling of the crisis will launch in April 2022 - but critics fear it will take years to report.
But the former No10 aide said the PM has no intention of sticking around for it's publication.
He wrote: "It will not start for years and it is designed to punt the tricky parts until after this PM has gone — unlike other PMs, this one has a clear plan to leave at the latest a couple of years after the next election, he wants to make money and have fun not ‘go on and on’."
Mr Johnson's press secretary hit back: "The PM has actually been asked this before and has said himself it's utter nonsense, so that still stands.
"As you know, the PM was elected in 2019 and continues to focus on delivering the manifesto we were elected on and leading the county out of the pandemic."
Brighty takes a poke at Mr Cummings in The Sun Credit: Brighty - The Sun Raab better than Johnson Taking a swipe at the PM, Mr Cummings praised Foreign Secretary Dominic Raab as a more effective manager during the Covid crisis.
As First Secretary of State, Mr Raab is the ranking Cabinet Minister and deputised when the PM was struck down with Covid.
Mr Cummings has sung his praises, saying meetings were "much more productive because unlike the PM Raab can chair meetings properly instead of telling rambling stories and jokes".
He also said that whenever confronted by a tricky question Mr Johnson would "shout ‘forward to victory’, [before] doing a thumbs-up and pegging it out of the room before anybody can disagree."
Before they became political enemies, former pals Boris Johnson and Dominic Cummings Credit: AFP What has happened so far between Dominic Cummings and Boris Johnson July 24, 2019: Boris Johnson hired Brexit mastermind Dominic Cummings to be his guru in No10.
He was taken on as a senior adviser to the new Prime Minister and was set to be a key figure in delivering Brexit.
Mr Cummings, a former aide to Michael Gove, effectively ran the Vote Leave campaign in the 2016 referendum.
He used data-driven campaigning to win over undecided voters by pushing a small number of key messages - and came up with the slogan "take back control".

His trip to Barnard Castle was to test his eye sight before returning to London, he claimed.
"My wife was very worried, particularly as my eyesight seemed to have been affected by the disease," he said.
He said he had gone to his parents’ farm with his wife and four-year-old son to protect his family and insisted he had behaved “reasonably and legally” as he defied deafening calls to quit.
Mr Johnson stood by him just a few hours later — but he did express contrition.

May 26 2021: The PM's ex-aide gave explosive evidence to the Commons health and science committees.
He apologised for ministers, officials and advisers falling "disastrously short" during the Covid pandemic.
"When the public needed us most the Government failed.
"I would like to say to all the families of those who died unnecessarily how sorry I am for the mistakes that were made and for my own mistakes at that," Mr Cummings said.
He said that at the start of the outbreak in 2020 the Department of Health was a "smoking ruin" and had "no plan" for how to shield the vulnerable.
He also claimed it initially had been "turning down ventilators because the price was being marked up" and its system for buying vital PPE equipment like masks and gloves was "just completely hopeless".
Accusing Matt Hancock of "criminal, disgraceful behaviour" that caused serious harm, he slammed him for only caring about hitting his testing targets.
And he fumed: "The Secretary of State for Health should've been fired for at least 15-20 things, including lying to everybody on multiple occasions in meeting after meeting in the Cabinet Room and publicly."
