UK's Johnson to quit as PM, Truss to take over
British Prime Minister Boris Johnson formally tenders his resignation to Queen Elizabeth II on Tuesday, handing over power to Liz Truss after his momentous tenure dominated by Brexit and Covid was cut short by scandal.. All eyes will be on her return to the British capital and first address as prime minister, which is expected to take place outside 10 Downing Street on Tuesday afternoon -- weather permitting.
