8. SOUNDBITE (English) Joanna Cherry, Scottish National Party lawmaker:

"And what's clearly coming to light, what's really clearly been emphasised today is the lack of candour on the part of the British Government about the reasons for the prorogation. Earlier today QC James Eadie, their lawyer, was asked if he could clarify what the reasons for the prorogation were and he wasn't prepared to do that other than by referring to the documents that have been lodged in court. But, it's been repeatedly emphasised today that there's no witness statements from the government accompanying those documents."

10. SOUNDBITE (English) Stefan Theil, Oxford University:

"So the main points for the government were obviously that this is not judiciable, that was the one that was really quite leant on heavily. Justiciability means 'is this a thing that a court should look in to?', in other words can and should the court deal with this case and look in to the lawfulness of the prorogation? For the applicants respectively, the main issue was well, this was unlawful, the Prime Minister misled the Queen when advising her to prorogue Parliament and is doing it for an improper purpose."

11. Exterior of Supreme Court

12. Stefan Theil, Oxford University:

"It is really hard to say. Whenever you feel like you get a sense of what the judges are thinking, they immediately ask a question that sort of turns that on its head. So it's really hard to say. They're keeping their cards really closely to their chest. It's difficult to say. I think the government had a pretty good day today, I would say that. But again, it's about the law, it's less about the symbolism and the theatrics, so we'll have to wait and see."

British Prime Minister Boris Johnson did not advise the Queen to suspend Parliament for five weeks for any "improper purpose", Supreme Court justices have heard.

Barrister James Eadie, representing the Prime Minister, told the 11-strong panel that the suggestion the prorogation was intended to "stymie" Parliament ahead of Brexit was "untenable".

At the end of the second day of the hearing, there were jeers from pro-Brexit campaigners as transparency activist Gina Miller, who helped to bring the action, left the court building.

Legal expert Stefan Theil said it had been a good day for the government in court, but it was unclear which way the judges would lean when they make their ruling.

The court is hearing appeals on two separate challenges in the English and Scottish courts over the prorogation of Parliament.

The justices will continue to hear submissions on Thursday, the third and final day of the hearing, but it is not yet known when they will give a decision.
