Scottish court delays decision on whether UK PM Johnson obeyed law

LONDON, Oct 21 (Reuters) - Scotland's top court has delayed a ruling on whether British Prime Minister Boris Johnson has fully obeyed a law which demanded he request a delay to Brexit.

Anti-Brexit campaigners had asked the court to keep monitoring Johnson, after he sent an unsigned letter to the EU requesting a delay but added another note in which he said he did not want a "deeply corrosive" Brexit extension, prompting some lawmakers to say he was seeking to frustrate the law.

"I am delighted with the Court's decision. It is a pity to have to say it, but this is not a Prime Minister who can be trusted to comply with the law," Jolyon Maugham, a lawyer involved in the case, said on Twitter.

"And because he cannot be trusted he must be supervised."
