Boris Johnson has declined to back any of the candidates vying to replace him as Conservative Party leader, suggesting his support could be damaging. The Prime Minister declined on Monday to give his public backing to any of the candidates running to succeed him as Tory leader after an extraordinary few days in Westminster that saw Mr Johnson unseated by an unprecedented revolt from within his own party. Mr Johnson, during a visit to the Francis Crick Institute, waved away questions over whether he felt “betrayed” by his own MPs, instead pledging to faithfully follow the established constitutional role of a caretaker Prime Minister. “I don’t want to say any more about all that,” he said. “There’s a contest under way and, you know, I wouldn’t want to damage anybody’s chances by offering my support.”
