Parliament voted Monday to stick with Mr. Ishiba, who will lead a minority government after his party suffered heavy losses in an election last month.

Japanese Prime Minister Shigeru Ishiba has survived a runoff vote against the opposition but will face turmoil ahead amid anger over the ruling party’s financial scandals.

The Japanese parliament on Monday re-elected Liberal Democratic Party chief Shigeru Ishiba as prime minister in a rare runoff vote after the ruling LDP lost its majority in the lower legislative chamber.
