The Prime minister (PM) of Lesotho, Pakalitha Mosisili, has lost a no-confidence vote in parliament, deepening the political uncertainty in the mountain kingdom ahead of a snap election likely within three months.

According to Ceoafrica, the vote yesterday against him as the head of a coalition government, came two years after his Democratic Congress (DC) ousted former prime minister Thomas Thabane's All Basotho Congress (ABC) by uniting with smaller parties.

Now it is Thabane's ABC that leads a coalition of opposition parties, including the Alliance of Democrats (AD) party, a group that split from DC last year, in an effort to remove Mosisili.

Members of parliament voted in favour of replacing Mosisili with Monyane Moleleki.

"The vote of no confidence motion to urge His Majesty King Letsie III to appoint Honourable Monyane Moleleki as the next prime minister has been carried", Speaker Ntlhoi Motsamai told Members of parliament after the vote.

Although, Mosisili has three days to either resign in favour of Moleleki or advise the king to call elections, which would be held within three months; but, Fako Likoti, Mosisili's political adviser, said the he would not step aside.

"He will continue to be the prime minister until we go for elections", Likoti told reporters.

Lesotho's last two elections have not produced a winner with a clear majority.

Completely landlocked by South Africa, Lesotho is one of the world's poorest countries and its economy is heavily dependent on its neighbour, to where it exports water and hydroelectric power.

Moreover, South Africa and the Southern African Development Community bloc have repeatedly called for peace and political reform in the country, but as a constitutional monarchy, Lesotho was a British protectorate known as Basutol, before independence in 1966.

The African country of two million people has been hit by several coups since independence.
