CAMPAIGNERS have won a High Court battle to force an MPs' vote on Brexit today in a crushing verdict for Theresa May.

Three judges have ruled that MPs must have a parliamentary vote on it before Britain cuts its ties, with significant implications for Robin Walker.

Worcester's MP was made a Brexit minister by the Prime Minister and is working with Cabinet Secretary David Davis on trying to forge the way forward.

The verdict from the High Court has stunned some politicians, with judges ruling that Mrs May does not have the power to trigger Article 50 - the two-year process for quitting the EU - without MPs' permission.

Just one of Worcestershire's six MPs backed Leave before June's vote, Redditch's Karen Lumley, but none are expected to defy the referendum result and block the process - especially as five of them are ministers.

Mr Walker called it a "sensitive" situation today and said the referendum result should be respected.

"The country voted to leave the European Union in a referendum approved by an act of parliament," he said.

"And the Government is determined to respect the result of the referendum - we will appeal this judgement."

But some county politicians now say the possibility of an early general election has dramatically shifted after the verdict.

Worcestershire UKIP MEP James Carver said: "Watch the odds shorten on an early general election, as Remainers stop at nothing to ignore a democratic vote."

Elsewhere some Worcester councillors who backed Leave hit out at the move, calling it "sour grapes".

They also voiced concern that the ruling will hamper Mrs May, in leaving her unable to keep key elements of the negotiations confidential.

Cllr Alan Feeney said: "So all the negotiating tactics must be debated in public, meaning you send Theresa May to play high stakes poker with all the cards facing up.

"I have never seen a more high-profile case of sour grapes."

Introducing his judgement, Lord Chief Justice Lord Thomas said: "This is a pure question of law.

"The court is not concerned with, and does not express any view about the merits of leaving the European Union - that is a political issue.

"The court does not accept the argument put forward by the Government - (it) does not have the power under the crown's prerogative to give notice to Article 50."

Mrs May was relying on ancient 'royal prerogative' to try and defeat campaigners, who in turn said it should not triumph the powers of elected MPs.

The Government has already vowed to appeal to the Supreme Court, with that verdict expected in December.
