Jeremy Corbyn has sacked Michael Dugher as Shadow Minister for Culture, Media and Sport as he completes the reshuffle of his frontbench team.
Mr Dugher had been expected to be moved on after publicly criticising the Labour leader on several occasions since September.
He is the first victim of Mr Corbyn's reshuffle, which is aimed at creating a more united Shadow Cabinet and to focus media attention away from the party's internal divisions and onto policy matters.
Mr Dugher revealed the news himself on Twitter and said Mr Corbyn had told him he "didn't like things I'd been writing", linking to an article he wrote for the New Statesman last week in which he warned the Labour leader against conducting a "revenge reshuffle".
Just been sacked by Jeremy Corbyn. I wished him a happy new year.— Michael Dugher MP (@MichaelDugher) January 5, 2016
Jeremy said he didn't like things I'd been writing (in defence of good colleagues & new politics). Well here it is https://t.co/prMdUislEe— Michael Dugher MP (@MichaelDugher) January 5, 2016
As recently as Sunday Mr Dugher warned Mr Corbyn not to turn Labour into "a religious cult", saying previous Labour leaders he had worked with had avoided going "down the path of big reshuffles”.
“They do try and hold the party together, they do recognise that the Labour party is a broad church, not a religious cult, that you need people of different backgrounds and try and get the best possible talents," he told Radio 5 Live's Piennar's Politics.
A host of Shadow Cabinet ministers have come out to praise Mr Dugher and mourn his departure.
Deputy leader Tom Watson, Home Secretary Andy Burnham and fellow shadow ministers Gloria de Piero, Luciana Berger, Lucy Powell, Vernon Coaker, Chris Bryant, Ian Murray and Jon Ashworth have all taken to Twitter to defend Mr Dugher.
Responding to the news, Mr Watson said: "Michael Dugher is a rare politician - a talented working class MP who hasn't lost his strong Yorkshire roots.
"Politicians with his ability and commitment can make a difference in any role. Labour's loss in the Shadow Cabinet will be compensated by Michael's free thought on the backbenches."
Really sorry to see @MichaelDugher leave Shad Cab. He will be missed!He will be just as ferocious attacking the Tories from the b/benches— Vernon Coaker MP (@Vernon_Coaker) January 5, 2016
Very sorry to see @MichaelDugher leave Shadow Cabinet. Michael is a formidable campaigner who provides an important & authentic voice.— Lucy Powell MP (@LucyMPowell) January 5, 2016
.@MichaelDugher is Labour to the core & has served our Party with distinction. He can leave the front-bench with his head held high.— Andy Burnham (@andyburnhammp) January 5, 2016
Disappointed that @MichaelDugher will not be around Shadow Cabinet table. A gr8 parliamentarian, super guy & ferocious opposer of injustice.— Ian Murray (@IanMurrayMP) January 5, 2016
They were joined by many backbench Labour MPs, who criticised Mr Corbyn's decision to remove Mr Dugher and said he was the kind of figure that was so important for the party's appeal in northern England.
Where's the broad church in all of this? Dugher is an effective communicator. Big mistake. https://t.co/PKgeSjSKh0— angela smith (@angelasmithmp) January 5, 2016
If getting rid of the Tories & electing a Labour government to implement Labour values is your thing, @MichaelDugher is your man. A big loss— Chuka Umunna (@ChukaUmunna) January 5, 2016

3/11 Stephen Doughty, Shadow Foreign Minister: RESIGNED

4/11 Pat McFadden, Shadow Europe Minister: SACKED
He was sacked as shadow Europe minister for "disloyalty" to leader Jeremy Corbyn
5/11 Pat Glass, Shadow Europe Minister: SAFE
Former junior shadow education minister Pat Glass replaced Pat McFadden as shadow Europe minister
6/11 Emily Thornberry, Shadow Defence Secretary: SAFE
She was promoted to shadow defence secretary. She is anti-Trident and therefore more in tune with Corbyn’s stance and replaces Maria Eagle, who was pro-Trident
7/11 Emma Lewell-Buck, Shadow Minister for Devolution and Local Government: SAFE
Emma Lewell-Buck was promoted to shadow minister for devolution and local government
8/11 Michael Dugher, Shadow Culture Secretary: SACKED
Outspoken critic of Jeremy Corbyn’s leadership, has been sacked as shadow culture secretary for his "incompetence and disloyalty"
9/11 Hilary Benn, Shadow Foreign Secretary: SAFE
Hilary Benn remains as shadow foreign secretary, but Corbyn’s team has insisted his role now comes with ‘new conditions’ that he must agree with Corbyn over foreign policy. Benn insists there are no ‘new conditions’ attached to his job and insisted: "I haven't been muzzled. I'm going to be carrying on doing my job exactly as before”
10/11 Maria Eagle, Shadow Culture Secretary: SAFE
Maria Eagle, moved from shadow defence to shadow culture secretary as part of Corbyn’s move to make his defence team match his anti-Trident views
11/11 Andy Burnham, Shadow Home Secretary: SAFE
Reports linked him to foreign secretary brief, but Corbyn appears to have backed down on sacking Hilary Benn. He does not see eye-to-eye with Corbyn on home affairs such as the Snooper’s charter, but removing your shadow home secretary so soon after starting would have been a dangerous move by Corbyn
Hilary Benn, the Shadow Foreign Secretary was widely tipped to be sacked too after his opposition to Mr Corbyn's stance on bombing Syria, but Mr Corbyn appears to have backed down from removing him.
But Maria Eagle is expected to be moved on from her role as Shadow Defence Secretary after publicly disagreeing with Mr Corbyn over his firm opposition to renewing Trident.
