Lesotho's former finance minister, Moeketsi Majoro, was sworn in as prime minister on Wednesday, a day after the resignation of Thomas Thabane, who quit after being accused of conspiring to murder of his wife.

Thabane attended Wednesday's swearing-in ceremony at the royal palace of King Letsie III, handing Majoro a copy of the constitution to formally signal the transfer of power.

Thabane stepped down following months of calls for his resignation over the murder of his estranged wife Lipolelo Thabane in 2017, just two days before he took office.

Majoro, who was first appointed into cabinet by Thabane in 2013, vowed Wednesday to usher in "a new version" of leadership and "bring back their (people's) trust to the government".

Majoro, who was aligned to Thabane in the divided ruling All Basotho Convention (ABC) party, emerged a consensus candidate to take over from Thabane.
