Lesotho’s Prime Minister Thomas Thabane officially tendered his resignation on Tuesday, ending a political crisis caused by his involvement in the assassination of his ex-wife in 2017.

The head of government had announced his retirement on Monday in a brief speech to the press.

80-year-old Thabane, who has been in power since 2017 will be replaced as head of government by the current finance minister, Moeketsi Majoro.

The head of government has been in the hot seat since the country’s courts suspected him, earlier this year, of involvement in the murder of his ex-wife, Lipolelo Thabane, a few days before taking office.

Under South African mediation, the coalition government then undertook to allow a “dignified” exit for the prime minister.
