The Prime Minister, Boris Johnson, is expected to announce his resignation as Conservative leader in a statement later today.
It has, however, been widely reported that he will seek to continue as Prime Minister until the autumn.
A No 10 spokesman said: “The prime minister will make a statement to the country today.”
It comes after Mr Johnson spoke to Sir Graham Brady, chairman of the Conservative backbenchers’ 1922 Committee, to inform him of his decision, a No 10 source said.
“The Prime Minister has spoken to Graham Brady and agreed to stand down in time for a new leader to be in place by the conference in October,” the source added according to the BBC.
It comes after a wave of cabinet and ministerial resignations on Tuesday and Wednesday, with East Hampshire MP Damian Hinds resigning as security minister on Wednesday morning.
