LONDON (AP) — The two candidates vying to be Britain’s next prime minister will face off in a TV debate Monday, after both sought to woo the Conservative Party’s right-wing base by backing a controversial plan to deport some asylum-seekers to Rwanda. Foreign Secretary Liz Truss and former Treasury chief Rishi Sunak are battling to succeed the discredited Boris Johnson as head of Britain’s governing party. They were chosen by Conservative lawmakers from an initial field of 11 candidates as finalists to replace Johnson, who quit as party leader on July 7 after months of ethics scandals triggered a mass exodus of ministers from his government.
