Theresa May has expressed "anger" at the Downing Street party saga and warned "nobody is above the law".
In a letter to constituents, the Tory former Prime Minister took a thinly-veiled swipe at Boris Johnson, saying people working in Government "should conduct themselves with the highest of standards".
Mrs May broke her silence in a message to voters, published by her local paper, the Maidenhead Advertiser, where she warned "full accountability must follow" if rules have been broken.
