Nicola Sturgeon has hit out at No10 after it was reportedly suggested by Downing Street sources that Scottish judges were "politically biased".

It comes after a legal bid to challenge the suspension of parliament succeeded at the Court of Session in Edinburgh.

After the Sun reported that Downing Street had attacked the ruling by Scottish judges as being “politically motivated”, the First Minister responded: “This is pitiful, pathetic and desperate from No10.”

Joanna Cherry added on Twitter: “Disgraceful slur on #judicialindependence. We chose the #Scottish courts because we are Scottish & they weren’t on holiday. The is the Supreme Court of Scotland & a higher court than the court of 1st instance in England.”

Justice Secretary Robert Buckland, commenting after reports a Downing Street source had suggested the Scottish judges were “politically biased”, said: “Our judges are renowned around the world for their excellence and impartiality and I have total confidence in their independence in every case.”

Ms Sturgeon also tweeted: “Today’s Court of Session judgment is of huge constitutional significance – but the immediate political implications are clear. Court says prorogation was unlawful and null and void – so Parliament must be recalled immediately to allow the essential work of scrutiny to continue.”

A group of around 70 parliamentarians had appealed against a ruling by a judge at the court that Boris Johnson's prorogation of Parliament is lawful.

Judge Lord Doherty originally dismissed a challenge against the suspension - which went ahead in the early hours of Tuesday - at the Court of Session last Wednesday, saying it is for politicians and not the courts to decide.

But three judges of the Inner House, the supreme civil court in Scotland, disagreed with Lord Doherty's ruling.

The UK Government plans to appeal against the latest ruling to the Supreme Court.

Former Tory attorney general Dominic Grieve said the ruling is a “serious indictment” on the Government.

Speaking to BBC News, Mr Grieve said: “I think the judgment is a serious indictment on the Government because, leaving aside whether the ruling in law is correct, it is quite clear that on the facts, the judges in Edinburgh concluded that the Government’s explanations for proroguing Parliament were simply inaccurate and untrue.”

He added: “We have been making the same point in the House of Commons.”
