Opinion | Who Will Be Britain’s Next Prime Minister?

Boris Johnson’s reluctant resignation this month as British Conservative Party leader and eventually Prime Minister is a chance for the country and his party to reset. It’s an opportunity the Tories have only partly seized as the race to succeed Mr. Johnson enters its last phase.

Tory lawmakers on Wednesday whittled the field to the last two candidates, from eight less than two weeks ago. Hundreds of thousands of registered party members across the United Kingdom will now choose between Rishi Sunak or Liz Truss in a mail-in ballot, with the winner—and thus the country’s new Prime Minister—to be announced in early September.
