The new Solomon Islands prime minister is Gordon Darcy Lilo.
Mr Darcy Lilo, who was one of the five candidates to contest today's vote in Parliament, got the backing of 29 of the 49 MPs.
He fills the post vacated by Danny Philip's sudden resignation last week.
Earlier last week Mr Darcy Lilo was sacked from Cabinet by Mr Philip.
There has been high security around Honiara in the lead up to the vote but our correspondents report it has been calm so far.
However the Solomon Star newspaper reported earlier today that the Malaita Masina Forum would stage a protest if Mr Darcy Lilo won the contest.
A spokesperson William Gua says they have never supported Mr Darcy Lilo because of allegations against him that have not been addressed.
The Malaita Masina Forum had wanted Central Honiara MP John Moffat Fugui or East Choiseul MP Manasseh Sogavare to become the country's leader.
