Alec Shelbrooke is the second MP to publicly back a motion of no confidence against the Speaker of the House of Commons – although more MPs are believed to be considering lending their weight.
Mr Bercow, who is required to remain politically impartial, recently accused Donald Trump of “racism and sexism” as he railed against an address by the US President in Parliament as part of a state visit later this year.
It has also since emerged the Speaker told students on 3 February that he voted to for Britain to stay inside the European Union during June’s historic referendum.
