Lesotho PM says he will resign as police probe first wife's death

Lesotho's prime minister has agreed to step down after evidence allegedly linked him to the murder of his estranged wife, his party announced on Thursday.

Police have issued an arrest warrant for Prime Minister Thomas Thabane's current wife, Maesaiah, for questioning over the murder of his first wife, Lipolelo, in June 2017.

Maesaiah failed to turn up for questioning on January 10 and police still do not know her whereabouts.

Senior members of Thabane's All Basotho Convention (ABC) party have accused the leader of hindering the murder investigation.

"Mr Thabane has already made known his decision to resign to the cabinet in its meeting on Tuesday," ABC spokesman Montoeli Masoetsa told AFP news agency on Thursday.

He said the next step for the party was to appoint a replacement, which would then need to be approved by parliament.

"There is no exact date in place as to when Thabane shall step down but it's going to be soon," Masoetsa added.

Pressure for Thabane's resignation had been mounting as more details emerged concerning the murder of Lipolelo Thabane, who was gunned down days before her husband was sworn in as leader of the small mountain nation in southern Africa.

At the time, Thabane denied involvement in his wife's death, describing the murder as "senseless." He officially married Maesaiah, whom he was publicly together with for years, in a civil ceremony shortly after Lipolelo's death.

The two women were engaged in a legal battle over who should be Lesotho's first lady at the time of the murder.

Polygamy is not legally recognized in Lesotho but is culturally normal, according to the UN. Lipolelo filed for divorce from Thabane in 2012 but the two were legally married until her murder.

The murder case was brought back to light last week when Lesotho's police chief Holomo Molibel released a public letter that said communication records from the day of the crime picked up Thabane's mobile phone number.

Since 2017, both Thabane and Maesaiah have been accused of corruption by critics
