Nominations to become David Cameron's successor as Conservative leader and UK prime minister should open this Wednesday (29 June) and close at noon on Thursday, an influential group of Tory MPs have proposed.
The executive of the 1922 Committee, which is made up of the party's backbench MPs and chaired by Brexit backer Graham Brady, also advised electing a new leader by 2 September.
The move comes after Cameron announced his intention to resign as prime minister and Conservative leader in the wake of the UK's decision to vote to split from the EU in a 23 June referendum.
Cameron, who was elected to the top of the Conservative Party in December 2005, had advised electing his successor by October.
Former Mayor of London Boris Johnson, chief spokesman of the successful Vote Leave campaign, is expected to run in the race as is Home Secretary Theresa May.
Brexit backers Andrea Leadsom, a former city minister, and Dr Liam Fox, a former defence secretary, have so far failed to rule out putting their names in the hat. Remain campaigner Nicky Morgan, the education secretary, has also hinted at running.
The 330 Conservative MPs, like the party's 2005 leadership election, will vote until two contenders are left, and the candidates will go head-to-head in a vote decided by the party's membership.
