The former head of the Civil Service who departed Government amid reported clashes with Dominic Cummings will today give evidence to the Covid Inquiry.

Lord Sedwill had served as cabinet secretary for two years until he resigned in September 2020. He was succeeded by Simon Case.

His appearance on Wednesday comes after explosive claims surrounding his time in office resurfaced during the evidence of other key figures. 

Last week, Boris Johnson’s former chief adviser Mr Cummings told the inquiry that Lord Sedwill losing his job “set off a kind of bomb across the whole system”.

Mr Cummings said he had “begged” the then-prime minister not to effectively sack the career civil servant, despite using obscenities to describe him in WhatsApp messages.

Lord Sedwill was also at the centre of allegations made by Mr Cummings about a plan to encourage people to hold the equivalent of “chicken pox parties” to promote herd immunity.
