Speaking at a meeting with the Foreign Press Association in London, Mr Bercow, 56, said: "I'm no longer the Speaker, I don't have to be impartial, so if you ask me if I think Brexit is good for our global standing, the honest answer is not, I don't think so".
"It's better to be part of the [EU] power bloc", he concluded, as cited by journalist Antonello Guerrera of La Repubblica, who attended the event in London. 31, 2019, he is stepping down just after 10 several years in the job.
Mr Bercow - who retired as Speaker on October 31 - added that it was "better" for the country to remain in the EU.
The position of speaker is supposed to be strictly impartial but critics frequently accused Mr Bercow of being biased against the government. "Parliament is no disgrace at all and did its job well". The speaker of Britain's Home of Commons has turn out to be a world-wide celeb for his loud ties, even louder voice and star flip at the center of Britain's Brexit drama.
Meanwhile BBC political editor Laura Kuenssberg said: "This will only confirm what Bercow's critics always believed... and he still won't do any United Kingdom interviews so we can't ask him about it yet".
Mr Bercow also said he agreed with the decision of the Supreme Court to rule the Prime Minister's decision to prorogue Parliament in September as unlawful.
None of the major parties are set to oppose Sir Lindsay Hoyle MP in the upcoming general election after he was voted in as the new Speaker of the House of Commons earlier this week..
During his decade-long stint in the Speaker's chair, Bercow championed the rights of backbenchers, making urgent questions a prominent part of the parliamentary day, for example.
I genuinely believe Sir Lindsay Hoyle has it in him to become one of the greatest Speakers we have ever had.
Sir Lindsay, formerly a deputy to Mr Bercow, received 325 votes to Mr Bryant's 213.
