One of Jeremy Corbyn’s senior aides, who wrote Labour’s last manifesto, has announced his intention to resign.
Andrew Fisher, head of policy, will leave his post by the end of the year “to spend more time with his young family”.
The Sunday Times claims Fisher warned that Mr Corbyn would not win the next general election.
It comes after Labour’s deputy leader Tom Watson called for unity on Saturday following a move to oust him at the start of the party’s annual conference.
In a statement seen by the BBC’s political correspondent Iain Watson, Mr Fisher said he is “choosing to prioritise” his wife and young son.
He plans to leave by the end of the year but says he will stay on should there be an autumn general election.
