Tory MP Angela Richardson has announced she has quit as a ministerial aide to Michael Gove, sharing her "deep disappointment" at the handling of the partygate row.
The move comes after senior civil servant Sue Gray released her report into events in Downing Street earlier today.
Despite featuring minimal information about the 12 gatherings now being examined by the Metropolitan Police, Prime Minister Boris Johnson and other senior ministers were blasted for "failures of leadership and judgement" in the account.
