She said: "What I have heard today from reliable sources is that the British Government are planning a legal challenge to the Benn Act, so I think the Supreme Court may be busy even after this week." 

The MP was part of a cross-party group of MPs and peers that won a ruling from the Inner House of the Court of Session that Mr Johnson’s prorogation decision was unlawful because it was “motivated by the improper purpose of stymieing Parliament”.

The so-called Benn Act requires Boris Johnson to get MPs to vote for a new Brexit deal or agree to a no-deal exit by 19 October or if he fails to do so, ask the EU for an extension to article 50 until 31 January 2020.

Today is the final day of a historic hearing at the Supreme Court in London, with a panel of 11 justices hearing submissions on behalf of Sir John, the Welsh and Scottish governments and Northern Irish victims’ campaigner Raymond McCord.

Those who brought the legal challenges argue the prorogation is designed to prevent parliamentary scrutiny of the UK’s impending exit from the EU on October 31.
