Boris Johnson resisted autumn lockdown as only over-80s dying: Dominic Cummings

Boris Johnson was reluctant to tighten Covid restrictions as cases rose last autumn because he thought people dying from it were "essentially all over 80", Dominic Cummings has claimed.

He also said the prime minister had messaged him to say: "I no longer buy all this NHS overwhelmed stuff."

Mr Johnson had wanted to let Covid "wash through the country" rather than destroy the economy, Mr Cummings said.

The claims came in an interview with BBC political editor Laura Kuenssberg.

It is the first time Mr Cummings - Mr Johnson's former chief adviser - has given a one-on-one TV interview during his career in politics.

In response, Downing Street said the prime minister had taken the "necessary action to protect lives and livelihoods, guided by the best scientific advice" throughout the pandemic.

And the government had prevented the NHS "from being overwhelmed through three national lockdowns", a spokesperson added.

In a wide-ranging interview, Mr Cummings also said that, near the start of the pandemic last year, Mr Johnson had wanted to keep his weekly face-to-face meetings with the Queen going - but he had to warn his boss that she might die if she caught coronavirus.

And he defended his controversial decision to drive to his parents' farm in County Durham after the first lockdown started, but admitted he had not "come clean" about all the reasons behind it, including "security concerns" around his family home in London.

This is the first major interview Mr Cummings has given, but he has answered MPs' questions on the government's response to Covid. The claims made at that session were explosive, but he's since been criticised for failing to provide the evidence to back up some of those assertions.

Covid cases dipped last summer but began to rise rapidly again as autumn started, prompting a debate within government about what measures were needed.

Mr Cummings told the BBC that he, UK chief scientific adviser Sir Patrick Vallance and England's chief medical officer Professor Chris Whitty had pushed for tougher restrictions from mid-September - Sir Patrick and Professor Whitty declined to comment.

Mr Cummings went on to allege Mr Johnson had said: "No, no no, no, no, I'm not doing it."

The prime minister had "parts of the media and Tory party screaming" not to increase restrictions and "always referred" to the Daily Telegraph, for which he had previously written a column, as "my real boss", Mr Cummings said.

On 13 October, with Covid deaths having risen to more than 100 a day, Labour leader Sir Keir Starmer called for a "circuit-breaker" lockdown of two to three weeks, but the government decided against this.

In a WhatsApp message sent on 15 October, shared with the BBC, Mr Johnson appears to have described himself as "slightly rocked by some of the data on Covid fatalities".

The "median age" for those dying was between 81 and 82 for men and 85 for women, the prime minister allegedly wrote, adding: "That is above life expectancy. So get Covid and Live longer.

"Hardly anyone under 60 goes into hospital... and of those virtually all survive. And I no longer buy all this NHS overwhelmed stuff. Folks I think we may need to recalibrate... There are max 3m in this country aged over 80."

He reportedly went on to write: "It shows we don't go for nationwide lockdown."

But the prime minister announced a four-week lockdown for England on 31 October, saying this was needed to protect the NHS as figures suggested deaths could reach "several thousand a day" without "tough action".
