The Supreme Court has ruled that Prime Minister Boris Johnson's advice to the Queen to suspend Parliament for five weeks was unlawful.

The decision means the prorogation is 'void and of no effect', and immediate steps can be taken to call MPs and Lords back to work. 

Lady Hale said: "It is important once again to emphasise that these cases are not about when and on what terms the United Kingdom is to leave the European Union.

"They are only about whether the advice given by the Prime Minister to Her Majesty the Queen... was lawful."

Lady Hale said the case is a "one-off", having come about "in circumstances which have never arisen before and are unlikely to ever arise again".

MP Dominic Grieve has already said he wants to return to Parliament as early as tomorrow. 

Lady Hale announced that the court's judgment was the unanimous judgment of all 11 justices.

She added that the court found the issue was "justiciable" - capable of challenge in the courts.

Lady Hale said the prorogation was "void and of no effect", adding: "Parliament has not been prorogued."

She continued that the speakers of the Houses of Commons and Lords "can take immediate steps to enable each house to meet as soon as possible".

Oxford East MP Anneliese Dodds said she was relieved the court ruled that parliament will be recalled.

She added: "Very large numbers of my constituents in Oxford East have been in touch to express their frustration about parliament being suspended.

"The suspension stopped me from asking questions about the impact of No Deal that I should have been able to - about the impact on BMW Cowley, our universities, medical supplies and food costs.

"I will be in parliament tomorrow and will do everything I can within that parliament to stand up for my constituents."

Oxford West and Abingdon MP Layla Moran said MPs needed to get back to work as quickly as possible.

She added: "The Government took unprecedented action that has been found to be unlawful.

"Parliament must now get back to work as quickly as possible.

"There is so much that MPs need to do to hold this government to account, and no time can be wasted.

"The thousands of people who marched on Broad Street in Oxford to call an end to Parliament’s suspension have been heard. This is a victory for the people."

Wantage MP Ed Vaizey tweeted: "The #SupremeCourt ruling reinforces the sovereignty of @UKParliament.

"I lost the conservative whip on the basis of upholding that sovereignty & now look forward to returning to work to deliver #brexit with a deal and the support of Parliament."

Banbury MP Victoria Prentis tweeted: "The ruling is a decision that we all need to digest & reflect on. I am in North Oxon on official visits but have a feeling my diary is about to change. I'll await further news & keep you updated, particularly in terms of events scheduled for my constituency."
