Thomas Motsoahae Thabane (born 28 May 1939) is a Mosotho politician who was the fifth prime minister of Lesotho from 2012 to 2015 and from 2017 to 2020. He founded the All Basotho Convention (ABC) in 2006 and led the party until 2022. Thabane served in the government of Prime Minister Pakalitha Mosisili from 1998 to 2006 as a member of the ruling Lesotho Congress for Democracy (LCD), but in 2006 he split from the LCD and launched the All Basotho Convention (ABC). After more than five years in opposition, he built a coalition of 12 parties in the wake of the 2012 Lesotho parliamentary election and was appointed Prime Minister. In the 2015 Lesotho parliamentary election, the ABC was democratically removed from power by a seven-party coalition led by Mosisili, though the ABC did win the most constituencies. Two months later, Thabane fled to South Africa with two other opposition leaders, claiming that their lives were in danger. They returned to Lesotho on 12 February 2017 to participate in a parliamentary vote of no confidence that unseated Mosisili. Thabane went on to win a plurality of seats in the subsequent parliamentary election and returned as prime minister. In 2020, Thabane faced pressure to resign as prime minister due to his alleged involvement in his ex-spouse's murder. He announced on 18 May that he would resign the following day. Political career Thabane served as Principal Secretary for Health under Leabua Jonathan, the second Prime Minister of Lesotho, until the military overthrew Jonathan in 1986. Thabane then served with the military regime under General Justin Lekhanya until 1991. He was Minister of Foreign Affairs from 1990 to 1991. Thabane became an advisor to Prime Minister Ntsu Mokhehle in early 1995. He subsequently served again as Foreign Minister in Mosisili's LCD government from June 1998 to June 2002, when he was appointed as Minister of Home Affairs and Public Safety. In November 2004 he was appointed Minister of Communications, Science and Technology. In opposition Thabane resigned from the government on 9 October 2006, and formed a new party, the All Basotho Convention (ABC). He claimed that his goal was to unite all Basotho, not only those from the Congress party or National Party. Some believed the ABC could lead Lesotho to economic development. 18 MPs crossed the floor to join the ABC in opposition on 13 October 2006; 17 of these (including
