Watch Emma full Hutchinson's interview with Daniel Zeichner above.
Only one of the region's MP voted against triggering Britain's exit from the European Union.
The Cambridge MP Daniel Zeichner defied the Labour whip to vote against.
The Norwich South MP Clive Lewis voted in favour of starting the Brexit process but says he might vote against at a later stage.
The region's only Liberal Democrat MP, Norman Lamb also defied his party's line to remain by abstaining on the vote.
Our Political Correspondent Emma Hutchinson spoke with Daniel Zeichner about why he had decided to defy the whip and vote against the bill.
Mr Zeichner spoke on a wide range of topics. On the benefits of the European Union:
Mr Zeichner was equally forthright on the Conservative party. He said it was worrying that they had been transformed from a pro-European, pro-Single Market party into an anti-EU group.
On his shadow Transport secreaty job I was quite surprised to be appointed in the first place, I've just got on with my job all the way through, when the Labour Party had problems last year I stayed. I'll go on with the job until someone tells me not to. When the country is so narrowly divided on this it seems to me this is different from normal circumstances, we live in strange time I'll have to see what happens.
And he vowed to fight on for the protections he believes could be lost when the country leaves the EU:
His stance, along with dozens of other MPs, have drawn criticism - notbaly from pro-Brexit campaigners like Nigel Farage.
The Commons overwhelmingly voted in favour of giving the government permission to start the process but there will be more parliamentary debate before the final decision.
