Supreme Court: Pictures from heated Commons debate Published duration 25 September 2019

MPs returned to the Commons on Wednesday after the Supreme Court ruled that Boris Johnson's decision to suspend Parliament was unlawful.

Supreme Court president Lady Hale said on Tuesday that it was unlawful because "it had the effect of frustrating or preventing the ability of Parliament to carry out its constitutional functions without reasonable justification."

Attorney General Geoffrey Cox told the Commons that he was "disappointed" at the landmark ruling but respected the judgement.

Here are pictures of some of the key political events this week.
