On Friday, London's High Court rejected a legal challenge against British Prime Minister Boris Johnson’s suspension of parliament before Brexit, but said it could be taken to the Supreme Court for an appeal, the BBC said.

Johnson announced at the end of August that he would suspend parliament from mid-September to mid-October, just before Britain is due to leave the European Union on October 31, so the government could announce a new legislative program.

His move evoked huge waves of protests across Britain over the past two weeks as hundreds of thousands of anti-Brexit protesters took to the streets shouting the slogan #StopTheCoup. 

More than 70 opposition lawmakers challenged Johnson's right to suspend or "prorogue" parliament, arguing it was illegal and unconstitutional because his intent was to force a no-deal Brexit by limiting the opportunity for opponents to object. 

A Scottish court on Wednesday ruled Johnson's decision as lawful, saying the matter was not one for judges to decide. 

The Scottish court was told on Tuesday that a memo passed to Johnson two weeks beforehand indicated he was looking to suspend parliament while his aides were publicly denying there were any such plans. 

The case is one of three legal bids to stop the prorogation. 

Campaigner Gina Miller, who defeated the government over another Brexit issue two years ago, is also taking a challenge to London's High Court on Thursday, a case backed by former Conservative Prime Minister John Major. 

Another case is due to be heard in Northern Ireland on Friday.
