Former British Prime Minister Boris Johnson - ousted by ethics scandals just three months ago - jockeyed to make a comeback on Oct. 21 as one of several contenders seeking to replace Liz Truss, whose rapid downfall threw the country's leadership into disarray at a time of severe economic challenges.

Contenders bidding to succeed Prime Minister Liz Truss were on Oct. 21 to open a hectic weekend of campaigning, but opposition parties demanded that UK voters get their own say to end months of political chaos.

The U.K.'s new Treasury chief ripped up the government's economic plan on Monday, dramatically reversing most of the tax cuts and spending plans that new Prime Minister Liz Truss announced less than a month ago. The move raises more questions about how long the beleaguered British leader can stay in office, though Truss insisted she has no plans to quit.
