Tanzanian President Jakaya Kikwete re-appointed Mizengo Pinda as prime minister of east Africa’s second largest economy.
Pinda, 62, has held the post since his predecessor Edward Lowassa resigned in 2008 over amid graft allegations.
The appointment was endorsed late on Tuesday by members of parliament, who voted 84.5 percent in favour of Pinda, Reuters reports.
The Tanzanian president was re-elected on October 31 in an election overshadowed by a low turnout and claims of rigging.
Kikwete, who took 61 percent of the vote, is due to address parliament on Thursday before naming his new cabinet anytime from Friday.
The presidential candidate of the opposition Chadema party, Willibrod Slaa, who got 26 percent of the vote, said on Monday his party would not recognise the election result.
