Pat McFadden has been sacked as shadow Europe minister - the second high-profile Labour MP removed from Jeremy Corbyn's top team for questioning the leader.
The MP has been forced out of the Shadow Cabinet over "disloyalty" to leader Jeremy Corbyn, and follows the sacking earlier in the day of Shadow Culture Secretary Michael Dugher.
In a highly unusual move, Labour sources made clear Mr McFadden was dumped for his cutting comments directed at Mr Corbyn in the aftermath of the Paris terror attacks.
Meanwhile, Emily Thornberry was appointed new Shadow Defence Secretary as the "revenge reshuffle" was completed.
The London MP replaces Angela Eagle, who moves to Culture, and opposes the renewal of the Trident nuclear weapons system, unlike her successor.
The move will have huge ramifications for Labour's Trident review, which will now be led by Ms Thornberry and former London mayor, who is also avowedly opposed to nuclear weapons.
After the atrocity in France, some Labour MPs attacked Mr Corbyn's refusal to distance himself from the Stop the War Coalition after it published a blog post saying Paris had “reaped the whirlwind of western support for extremist violence in the Middle East”.
During Prime Minister's Questions, Mr McFadden said blaming the West risked "infantilising the terrorists" and "treating them as children".
His full comments were:
"Can I ask the Prime Minister to reject the view that sees terrorist acts as always being a response or a reaction to what we in the West do? Does he agree with me that such an approach risks infantilising the terrorists and treating them as children when the truth is they are adults entirely responsible for what they do?”
Mr McFadden will be replaced by Pat Glass, who was the shadow education minister, as the referendum on whether Britain should leave the EU looms.
Some Labour MPs, as with Mr Dugher, reacted with anger - calling the party leadership a "shower" and being guilty of "intolerance", and calling the decision "vindictive and stupid".
Some 10 members of the Shadow Cabinet voted for RAF airstrikes in Syria, which is said to be fuelling the Labour leader’s re-arrangement of his top team.
Mr McFadden tonight acknowledged the point forwarded at PMQs was the reason for his demise.
Mr Dugher took to Twitter yesterday morning, straight after a getting a phone call from Mr Corbyn, to announce he had been "sacked" - then added it was because Mr Corbyn “didn’t like things I’d been writing (in defence of good colleagues and new politics)”.
