Lesotho’s prime minister has bowed to pressure to step down over evidence allegedly linking him to the murder of his estranged wife.

Senior members of the All Basotho Convention (ABC) party have accused Thomas Thabane of hampering investigations into the killing. They called for his resignation last week.

In June 2017, unidentified assailants gunned down his wife, Lipolelo Thabane, 58, on the outskirts of Lesotho’s capital Maseru, two days before her husband’s inauguration.

The brutal murder was brought back into the limelight last week by a letter from Lesotho’s police chief Holomo Molibeli.

It claimed that communication records from the day of the crime picked up Thabane’s mobile phone number.

The letter – dated December 23, 2019 – became public in court documents filed by Molibeli after Thabane tried to suspend him over a separate matter.

“Mr Thabane has already made known his decision to resign to the cabinet in its seating on Tuesday,” ABC spokesman Montoeli Masoetsa told AFP 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.

Lipolelo’s murder sent shock waves through the tiny poverty-stricken nation, which is entirely ringed by South Africa.
