That's all from Holyrood Live on Tuesday 24 September 2019, a quite remarkable day in UK politics.
The first minister called on Boris Johnson to resign after the Supreme Court ruled that his decision to suspend Parliament was unlawful.
Nicola Sturgeon said the prime minister's behaviour shamed the office of prime minister, the UK government and the Conservative Party.
She told MSP the ruling by the Supreme Court was "truly historic and unprecedented".
The first minister said: "It's hard to think of a democratic country where there has been a more damning vierdict on the behaviour of a prime minister."
Mr Johnson, who is currently in the US, told the BBC he "strongly disagrees" with the ruling but will "respect" it.
The prime minister suspended Parliament - a process known as proroguing - for five weeks earlier this month.
