The controversial figure is facing a vote of no confidence after Tory MPs questioned how Mr Bercow could now be seen as neutral during parliamentary Brexit debates after revealing he voted to Remain in the historic EU referendum.
James Duddridge, the Tory MP who tabled the motion of no confidence, claims Mr Bercow is “courting controversy” and should quit his role.
The MP for Rochford and Southend East tabled the motion after the Sunday Telegraph revealed Mr Bercow’s anti-Brexit comments at Reading University.
Sky News has since released a video of the Speaker making more pro-Remain comments to students at Sheffield University.

I’ll probably get into trouble for saying this, but I didn’t vote for Brexit
On October 27, Mr Bercow again publicly declared his support support for Remain, however, denounced any idea of a second referendum.
Answering questions on Brexit, he claimed it “would have been politically dangerous for the Speaker” to pursue an agenda for one side or the other.
The Speaker added: “So I didn’t and even now I’m not sure that I should have done.”
Despite his uncertainty he proceeded to give his own view on Brexit, he said: “I’ll probably get into trouble for saying this, but I didn’t vote for Brexit, ok…
“So that was my position and I have no apology for that.
“However, I am a democrat and I think that the idea of a second referendum is absolutely for the birds.”
Speaking on BBC Radio 4’s Today programme, Mr Duddridge accused Mr Bercow of using the Speaker’s chair “to pontificate on international affairs” after he also spoke out against Donald Trump’s proposed state visit to Britain.

He added: “In the House of Commons, he quite frequently calls his friends rather than being totally impartial but critically now, he can no longer be impartial given he’s expressed views so publicly and clearly.”
Mr Duddridge then called on Mr Bercow to stand down as Speaker for discussing “policy issues”.
