Labour's deputy leader Tom Watson has said Jeremy Corbyn "needs more time" to "set out his stall" as party leader.
It comes after an election night which saw the party lose a number of seats across the UK - though they have performed better than expected in England so far.
Mr Watson said Labour suffered a devastating loss in last year's general election, meaning this year the party was "coming from low base".
"We've got some way to go," he added.
He also paid tribute to the members who lost in the Scottish Parliament elections, with the Tories making unexpected gains to become the second biggest party in Scotland.
Labour leader hits out at a harmful "running commentary" in the media as he admits the party is not in a position to win the next election.
MPs say the results show that Jeremy Corbyn's brand of socialism isn't working - but he has done well enough to stave off a coup.
A Labour MP opposed to Jeremy Corbyn just texted me: he has until next year to prove he can win the General Election in 2020.
