LONDON, Sept 11 (BBC): Boris Johnson's suspension of the UK Parliament is unlawful, Scotland's highest civil court has ruled.
A panel of three judges at the Court of Session found in favour of a cross-party group of politicians who were challenging the prime minister's move.
The judges said the PM was attempting to prevent Parliament holding the government to account ahead of Brexit.
A UK government appeal against the ruling will be head by the Supreme Court in London on Tuesday.
The Court of Session decision overturns an earlier ruling from the court, which said last week that Mr Johnson had not broken the law.
It is currently unclear what impact the judgement will have on the current five week suspension of Parliament, a process known as proroguing, which started in the early hours of Tuesday.
Opposition parties have called for Parliament to be immediately recalled, but government sources have told the BBC that the demands would be rejected.
MPs are not scheduled to return to Parliament until 14 October, when there will be a Queen's Speech outlining Mr Johnson's legislative plans. The UK is due to leave the EU on 31 October.
