Said the Foyle MLA: “Boris Johnson has been found to have acted unlawfully.
“He sought to silence his critics and suspend democratic scrutiny of his government. He cannot be in office a second longer.
“Opposition parties must move immediately to table a vote of no confidence against the British Government and stop Boris Johnson.
“If the DUP has any sense of what is right, they will withdraw their support for Johnson as well.
“A vote of no confidence will make way for a temporary administration at Westminster that can stop no deal, protect our economy and at last put the power back to the people in a general election.
“This has gone on too long.
“Opposition leaders need to take on the Tories and take out Boris Johnston.
“Ireland’s interests are on the line at Westminster, there is a fight to be had and this is no time to be standing on the sidelines.
“There’s no time to waste – respect the court, take a stand and send the Prime Minister packing,” added Mr Eastwood.Tags:
