A Teesside MP and who said Jeremy Corbyn was like the "Wizard of Oz" has congratulated him after he retained the Labour leadership.
Redcar MP and Corbyn-critic Anna Turley has now urged the Labour Party to unite following the result.
The Labour leader polled 61.8% of the vote in his leadership battle with Owen Smith, adding it was time to "wipe the slate clean" within the fractured party.
The veteran socialist had been strongly criticised in the build up to the vote by Ms Turley, who openly championed the Smith campaign.
Branding Corbyn "the Wizard of Oz", she claimed he was "completely out of touch with reality" after quitting his shadow cabinet.
But following Corbyn’s victory, she has congratulated him on Twitter.
And she added: "We must look like a government in waiting. For all British people, not just the ones who share our views.
"We must apply our traditional Labour values to today’s and tomorrow’s local and global social and economic challenges and be in tune with the public.
"We must set forward positive and concrete Labour solutions to the daily fears and concerns they face.
"But it is vital now that we listen to the electorate.
"We cannot just shout at them with slogans and flags and ideals."
Elsewhere, Middlesbrough MP and Shadow Secretary of State for Transport Andy McDonald tweeted his congratulations to the Corbyn camp.
Mr McDonald, an ally of the divisive leader, added the Labour party was one "with far more that unites us than divides us".
Labour’s other Teesside MPs, Tom Blenkinsop and Alex Cunningham, have so far remained tight-lipped on social media regarding their views about Corbyn’s re-election.
The Labour leader was Ms Turley’s MP in Islington, and supported her big to become Redcar’s MP in 2015.
But in her resignation letter when she left her role as Shadow Minister for Civil Society, she claimed that while he was one of the "kindest and most committed public servants in politics", he lacked the "strong, forward-looking and competent leadership" she feels the party needs.
