"I think that the idea that we will march through the exit door is extremely unlikely," Speaker John Bercow told students during a lecture at Vilnius University in Lithuania.
"We will remain in, we will argue, there will be disagreements, there will be compromises but we will be part of the European Union," Bercow added.
A Harris Interactive poll published on Monday in the Financial Times showed 50 per cent of Britons would vote to leave the bloc, 33 per cent would vote to stay in and 17 per cent would not vote.
Bercow today insisted that most members of parliament want to stay in the EU, adding he was convinced "that will be the verdict of the British people as well" in case of a referendum.
"They may grumble, they may criticise, they may argue for change but will they want to go marching through the exit door? I do not believe they will," Bercow said.
