Both of the candidates looking to succeed Boris Johnson say they back — and would even expand — the ousted prime minister’s controversial plan to send illegal immigrants in large numbers to the African nation of Rwanda, a plan sharply denounced by immigrant and human rights groups in the U.K.
Rishi Sunak, Mr. Johnson’s former chancellor of the exchequer and the son of African-born parents of Indian descent, and rival Liz Truss, the foreign secretary, made clear they back the Rwanda plan as they face a vote of Conservative Party members nationwide to replace the scandal-plagued Mr. Johnson.
