All four of the UK's chief medical officers rejected suggestions from No 10 that the coronavirus threat level could be reduced because it contradicted evidence that showed the virus was still widespread, the Guardian has been told.

A senior source in one devolved government said the chief medical officers of England, Scotland, Wales and Northern Ireland discussed and refused Boris Johnson's proposal.
