PETER Kyle has joined his fellow city MP in saying he would rebel and vote against Brexit if the terms are not right.

Hove's Labour MP said there was too much uncertainty on the economy and too many broken promises for him to vote to start Britain's withdrawal from the EU now, adding he would only do so in the future if he felt it was right.

He joins Brighton Pavilion MP Caroline Lucas and Tory grandee Ken Clarke, an MP in Nottingham, in stating their willingness to vote against the 52 per cent yes vote from the national referendum in June.

Their comments follow Wednesday's landmark High Court ruling, being appealed, that issuing Article 50, the mechanism to start Brexit, needs parliament's approval.

Staunch pro-Brexit MP Henry Smith said they were behaving outrageously and the referendum should be respected.

Mr Kyle, who campaigned for Remain, told The Argus: "If there was a vote today or tomorrow I would vote against Article 50 and that's for the very simple reason that the British government has failed to articulate a destination for the British economy that is better than the one we have today.

"Article 50 before the government has done everything in its power to articulate a vision for Britain outside of Europe would be an act of vandalism against our economy and the biggest price would be paid by the vulnerable.

"We need to respect the vote of the 52 per cent but we need to make sure they get what they voted for.

"Right now they, as well as the 48 per cent, are being badly let down.

"At the moment the Government is asking us to walk through a gate without any idea of what is behind. I want the promises that were made to be delivered."

Among the promises made by Brexiteers that were already falling apart, he said, were on new trade markets, restrictions on free movement, and £350 million extra cash for the NHS.

Mr Kyle said he would vote to trigger Article 50 at a later date "if I believe that Britain has the potential to thrive in the way that has been articulated outside of the EU".

He added: "I would never vote in any way that I felt would harm the community that elected me. There is nothing in the constitution about a referendum but there is a lot about MPs doing what is in the best interests of our weak.

"I believe that if in my heart I believe that by submitting Article 50 we will damage either our society, our economy, or a significant part of our population, then I cannot in conscience do it."

On Wednesday Ms Lucas told The Argus she would defy the referendum result if a Brexit deal threatened the economy, environment or safety of Brighton residents.

Brighton Kemptown MP Simon Kirby told The Argus he would vote for Article 50, saying "we should respect the result of the referendum".

Crawley's Tory MP Henry Smith told The Argus yesterday he was disappointed with the High Court's ruling on Wednesday and backed the Government's planned challenge to the Supreme Court.

He added: "I think it is the duty of MPs to vote in accordance with what the British people want.

"For anybody who has been the beneficiary of public office through democracy, to seek then to deny a democratic choice is outrageous."
