British Prime Minister Boris Johnson suffered a blow to his authority on Thursday when lawmakers triggered an investigation into whether he had misled parliament.

Boris has been fighting for political survival for months after he told parliament that his Downing Street office had followed all lockdown rules during the Covid pandemic, only for an internal report to find it had held alcohol-fuelled parties at that time. Police have since fined Boris.

During a parliamentary debate politicians from all sides called on Boris to go, and lawmakers backed an Opposition motion that his statements “appear to amount to misleading the House” and should be investigated by its Committee of Privileges.

“I don’t want this thing to endlessly go on. But I have absolutely nothing, frankly, to hide,” Boris told Sky News when asked about the investigations in India.
