Dominic Cummings will make an unprecedented public statement today over his 260-mile drive in the midst of the coronavirus lockdown.
Downing Street confirmed the PM's top advisor will make the highly unusual move hours after his actions were defended by the Prime Minister.
He is also expected to take questions. The time of the statement has not been confirmed. The government's press conference is still expected to go ahead today and could be led by the PM.
It is almost unheard of for senior aides to make public statements. Usually any communication takes place behind closed doors on behalf of their boss.
