Reactions to historic Supreme Court ruling

Elaine Motion, executive chairman of Balfour+Manson, which represents Joanna Cherry MP and all other petitioners in the case initially brought at the Court of Session, said:

"The unanimous decision of the UK Supreme Court today, to cut down the prorogation, essentially reconfirms the position taken by the Court of Session Inner House. That means that the clock is rewound to 27 August and Parliament is not suspended. It is as if the suspension never occurred.

"It is a huge vindication for the parliamentarians who led the way with the challenge in Scotland, and an even more significant reinforcement of the critical importance of the rule of law and the sovereignty of Parliament. Hopefully Parliament can now get back to its essential work."
