UK Prime Minister Boris Johnson's Conservative working majority in parliament -- which was down to a single vote -- is now gone, as former Minister Philip Lee dramatically walked over to the LibDem bench and joined the opposition in the middle of a Johnson speech. Lee had long been a pro-Remain voice in the party, but said the final straw was arch-Leaver Jacob Rees-Mogg mocking the doctor who had written the official report on the healthcare consequences of a no-Deal Brexit -- one in which he warned that increased patient mortality was a likely result.
At the same time, parliament dealt a huge blow to Johnson by voting to preserve their authority to stop a no-Deal Brexit. Twenty-one Tory MPs bucked the party (and braved threats of expulsion from the Conservative ranks); Johnson has sworn to call early elections in response.
UPDATE: The Tory rebels have had their whips removed and now sit as Independents.
