Prime Minister Boris Johnson has sent an unsigned letter to the European Union requesting a delay to Britain’s exit from the bloc, as well as a second note saying he did not want a “deeply corrosive” Brexit extension. Johnson was required by law to send the first letter, after parliament voted on Saturday to withhold its approval of his Brexit deal until it has passed legislation to formally ratify the agreement. Jacob Rees-Mogg, leader of the lower house of parliament, or House of Commons, said on Saturday the government planned to put Johnson’s exit deal to a debate and vote on Monday.
