Senior Tory says UK PM should quit if rules broken World May 3, 2021 LONDON: A senior British Conservative broke ranks on Sunday to call for Prime Minister Boris Johnson’s resignation if it is proven that he broke government rules over the funding of a lavish revamp of his Downing Street flat. The call from Douglas Ross, leader of the Conservatives in Scotland, came as new opinion polls showed the ruling party’s lead over the main opposition Labour party has been slashed, ahead of British local elections on Thursday. Foreign Secretary Dominic Raab said the Conservative party took seriously an investigation by the powerful Electoral Commission into the apartment funding, but dismissed the allegations as "tittle-tattle".
