"This really is a landmark judgement and it gives the lie to all of those that said the prorogation of parliament, the shutting down of the Westminster Parliament - deliberately to try to avoid scrutiny and debate - was lawful.
"The Supreme Court has ruled unanimously, backing the Scottish Court of Session, that this was not lawful, so it really does behove the current Tory MP for Stirling, Stephen Kerr, to apologise for his grossly irresponsible statements backing prorogation and backing a reckless Prime Minister who has taken the limits of the UK constitution and demonstrated that he is willing to trash them. We need people to stand up to that, not go along with it like Stephen Kerr has done so far.
"He should apologise now to the people of Stirling and he should get back to work in Westminster and try representing his constituents who voted overwhelmingly to remain within the European Union. Even people who voted Leave didn't vote for this chaos. He needs to get his act together and start working for the people of Stirling."
