BORIS Johnson did say "let the bodies pile high in their thousands" according to his former chief adviser.

Dominic Cummings was pressed on whether the Prime Minister made the statement ahead of a second coronavirus lockdown being introduced in November of last year.

Cummings has been facing questions from MPs on the joint Science and Technology Committee and Health and Social Care Committee about the UK Government's response to the Covid pandemic.

He was asked about alleged statements made by Johnson by SNP MP Carol Monaghan, a member of the Science and Technology Committee.

Monaghan asked Cummings: "Did you hear him say 'let the bodies pile high in their thousands' or 'it's only killing 80-year-olds?"

Cummings replied: "There's been a few different versions of these stories knocking around.

"There was a version of it in the Sunday Times which was not accurate, but the version that the BBC reported was accurate."

He was then asked: "And you heard that (Boris Johnson saying those comments)?"

The former adviser responded: "I heard that in the prime minister's study.

Cummings went onto say that the Prime Minister made the statement "immediately after" he made the decision to introduce the second lockdown on October 31.

Johnson has denied that he made the remark, saying in April that the claims were "total, total rubbish".

Earlier in his evidence session to MPs today, the former chief adviser to the Prime Minister also claimed that Johnson considered being injected with Covid-19 on live TV to prove the virus was not serious.

Cummings suggested that Johnson – who later became critically ill with Covid 19 – had considered being injected with coronavirus by chief medical officer Professor Chris Whitty.
