British Deputy Prime Minister Dominic Raab resigned from the government on Friday following an independent investigation into complaints that he bullied colleagues, the latest scandal to force out one of Prime Minister Rishi Sunak’s top ministers, writes Reuters.

The loss of the third senior minister over their personal conduct in the last six months will damage Sunak’s efforts to revive the governing Conservative Party’s fortunes and is a major embarrassment as he had entered Downing Street in October promising a government of integrity.

Raab resigned in a letter to the prime minister before the report was made public, and his departure is a setback for Sunak just two weeks ahead of English local council elections where his Conservatives are predicted to fare badly.

“I called for the inquiry and undertook to resign if it made any finding of bullying whatsoever”, - Raab’s letter said. “I believe it is important to keep my word”.

Sunak said in a letter in reply that he accepted Raab’s resignation with deep sadness but said it was important that ministers uphold the highest of standards.
