John Major will take the stand in the case against Boris Johnson's decision to suspend Parliament, it emerged last night.
In an unprecedented development, the former Conservative leader will appear at the Supreme Court on Thursday in a case which will decide whether Mr Johnson acted illegally by proroguing Parliament earlier this month.
Sir John will be a lynchpin in the case brought by pro-Remain businesswoman Gina Miller, who said the Prime Minister may have breached 'the legal principle of Parliamentary sovereignty' and that the act represented an 'abuse of power'.

Yesterday, another former Tory prime minister, David Cameron, accused Mr Johnson of 'sharp practice' for proroguing Parliament.
But Mr Johnson said it was 'claptrap' for people to say he had stopped MPs having their say on Brexit.
He told the BBC: 'All this mumbo jumbo about how Parliament is being deprived of the opportunity to scrutinise Brexit.
'What a load of claptrap. Actually, Parliament I think has lost about four or five days.'
And senior Tories last night claimed that the Prime Minister is ready to ignore a controversial law pushed through Parliament forcing him to seek another Brexit delay if a deal is not reached by October 19 – even if it means he is dragged to court.sonos sonos One (Gen 2) -
