Britain’s Boris Johnson was clinging to power on Wednesday, with support seeping away from the increasingly isolated prime minister, badly wounded by the resignation of a stream of senior colleagues who said he was not fit to govern. 

Johnson’s finance and health secretaries quit on Tuesday following the latest scandal to hit the government, triggering the departure of around 15 lower-ranking politicians and the withdrawal of support of once loyal lawmakers. With the tide of resignations rising, some questioned whether the prime minister could fill the vacancies.
