JONATHAN Edwards has called on Boris Johnson to resign after the Supreme Court ruled that his decision to prorogue Parliament was unlawful.

The Carmarthen East and Dinefwr MP said that Parliament must be recalled immediately after the Supreme Court has ruled that the prorogation of Parliament was unlawful.

All four Plaid Cymru MPs were amongst a small number of petitioners in the case first heard in the Scottish Court of Session and subsequently the appeal today at the Supreme Court.

Plaid Cymru MP, Jonathan Edwards said: “The Supreme Court has delivered a damming and unanimous verdict.

"Boris Johnson has broken the law for undermining the basic principles of democracy.

"The Prime Minister has shown himself to be no better than a tin-pot dictator, shutting down democracy to avoid scrutiny.

“There is no question, the Prime Minister must resign immediately and a crash out Brexit stopped once and for all.

“In his short time in office Boris Johnson has proven himself to be a deeply dangerous and anti-democratic leader, with no respect for the rule of law.

"It would be a complete affront to civilised society if the Prime Minister did not resign after this historic ruling.”
