As many as eight shadow ministers would quit in protest if shadow foreign secretary Hilary Benn is sacked in Labour's reshuffle, a member of the shadow cabinet has told ITV News.
It is now thought that Mr Benn will not be removed from his role, despite earlier speculation suggesting he would be the most high-profile victim of what was dubbed the "revenge reshuffle".
It had been suggested that Mr Benn's position was in doubt after he opposed leader Jeremy Corbyn on whether to extend airstrikes against Islamic State in Syria.
Only the axing of shadow culture secretary Michael Dugher has thus far been announced during the reshuffle.
A planned shadow cabinet meeting has been cancelled amid an ongoing Labour reshuffle, reports ITV News Political Correspondent Libby Wiener.
Shortly before, shadow foreign secretary Hilary Benn - who is now thought likely to keep his job - had been seen arriving to meet leader Jeremy Corbyn.
A number of senior Labour figures have offered their tributes to Michael Dugher after he was sacked from the shadow cabinet by Labour leader Jeremy Corbyn.
Among those to lend their support were shadow home secretary Andy Burnham, whose campaign for the leadership was led by Mr Dugher.
He tweeted that the Barnsley MP was "Labour to the core and has served our party with distinction".
.@michaeldugher is Labour to the core & has served our Party with distinction. He can leave the front-bench with his head held high.
Another minister, Gloria de Piero, said she was sad to lose someone from an "ordinary background" from the shadow cabinet, while shadow education secretary Lucy Powell said she was "very sorry" to see Mr Dugher leave.
Mr Dugher claimed he had been "sacked" because Mr Corbyn didn't like "things I'd been writing", partly referencing attacks on the Momentum campaign group which backs the Labour leader.
Jon Lansman, a founder of the group, wrote on Twitter that Mr Dugher had done a "disservice" to Mr Corbyn and was partly to blame for Mr Burnham's failure to become leader.
Shadow culture secretary Michael Dugher says he has been "sacked" as Jeremy Corbyn holds his first reshuffle since becoming leader.
Just been sacked by Jeremy Corbyn. I wished him a happy new year.
The Barnsley MP, who had previously criticised Mr Corbyn in the media, said he wished Mr Corbyn a "happy new year" after being informed of the decision.
In a later tweet, Mr Dugher said Mr Corbyn had told him "he didn't like things I'd been writing", such as a New Statesman article urging him not to remove shadow ministers who had voted against the leader on extending airstrikes to Syria.
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
According to ITV News Deputy Political Editor Chris Ship, Mr Dugher was told over the phone that he would be losing his job.
Hilary Benn appears set to keep his job as Labour's shadow foreign secretary, while shadow defence secretary Maria Eagle looks likely to be given a new role, ITV News' Deputy Political Editor Chris Ship reports.
Both MPs had been linked with moves away from their current positions in what was dubbed a "revenge reshuffle", after they publicly disagreed with leader Jeremy Corbyn on key policies.

Mr Benn opposed extending airstrikes against Islamic State in Syria - even making a speech in opposition to Mr Corbyn ahead of a Commons vote on the move.
Ms Eagle also differed with the leader's view by favouring the renewal of Trident, Britain's nuclear deterrent, and described Mr Corbyn's public opposition to the programme as "not helpful".
It is thought that if Ms Eagle is removed from the defence brief, she could be replaced by Lisa Nandy, who is currently shadow energy secretary.
