Thabane ordered a strike on Lipolelo Thabane to allow Maesaiah’s current wife to become the first lady, Lesotho police commissioner Paseka Mokete said in a statement.
Lipolelo Thabane was shot dead by gunmen near her home in the capital, Maseru, in June 2017.
She negotiated a divorce from Thabane before her death.
The documents state that the prime minister and his wife allegedly met with the leader of a gang and promised them $ 177,000 and work to kill Lipolo before his inauguration as prime minister, police said in a statement.
Thabane also shared his ex-wife’s home address with her killers and began monitoring the Lipolelo movement, police said.
They tried to kill Lipolo on June 12, but failed and reported the incident to police, according to Moquet.
They then shot and killed Lipololos two days later on her way from a meeting with an anonymous mediator, who is now a state witness.
The mediator negotiated a truce between the two women in Ficksburg, a small town in neighboring South Africa, according to the affidavit.
Thabane married Maesaiah’s current wife two months after Lipolelo’s death.
Maesaiah was charged with the murder of Lipolelo and the attempted murder of another woman who was with the former first lady when she was killed.
The former prime minister has not been charged despite police efforts to oust him. His lawyers claimed that he had immunity due to his position.
Taban resigned from his post in May after months of pressure from his party to resign over his alleged involvement in the case.
He will be charged with murder now that he is no longer in power, Moquet said.
Police arrested Maesaiah again last week and her previous bail was revoked for technical issues.
The court ordered a new bail application and said a different judge should hear the case.
