Sir John Major has warned it is "unwise" for Boris Johnson to stay in Downing Street as his successor is chosen as Tories react to the PM's speech with shock.
The former Prime Minister published his letter to Sir Graham Brady, the chairman of the 1922 Committee, which suggested a caretake PM would be in the "national interest".
Mr Johnson acknowledged his resignation will provide "relief" to many people, but his speech has prompted shock and fury amongst many.
