Culture Secretary's don't seem to last very long these days and indeed Hancock, who now moves up to replace Jeremy Hunt MP as the UK Health Secretary, was only promoted to the position of Culture Secretary in January 2018 when he replaced Karen Bradley MP (here).
Mr Hunt leaves the Department of Health and Social Care (DHSC) after having secured a £20 billion-a-year funding increase for the NHS.
Mr Hunt said it was a moment to show that Britain remained a "strong, confident voice in the world".
Earlier, staunch Brexiteer Dominic Raab was named as Mr Davis's replacement as Secretary of State for Leaving the EU.
Johnson, who served as foreign secretary, was the face of the Brexit campaign.
However the Daily Mail reported Mr Rees-Mogg said Mr Johnson would make a "brilliant" prime minister.
"It is as though we are sending our vanguard into battle with the white flags fluttering above them", Johnson wrote in a letter that underscored his credentials as a champion of full-speed Brexit.
"As we developed our policy on Brexit, I have allowed Cabinet colleagues considerable latitude to express their views", she said in her letter of response to him. "What the Prime Minister needs to do is to give up on the Chequers proposal ... which does not actually deliver Brexit", he told LBC Radio.
Nevertheless, many Brexiteers were furious after Downing Street said it would be be briefing Labour MPs on the Chequers plan.
Sir Graham has consistently refused to say whether he had received any such letters.
And asked whether Mrs May would fight a no-confidence vote if one was called, a senior Number 10 source said simply: "Yes".
"And it would be a split coming from the top, not from the members of the Conservative Party across the country".
