Samoan Prime Minister Tuilaepa Sailele Malielegaoi was among those who witnessed the Prime Minister being blessed by village elders and a church minister.

A local reporter speaking on Auckland-based Radio Samoa said many people had gathered to witness the ceremony.
The honour for the Prime Minister comes after Independence Day celebrations were held in Samoa, celebrating 55 years of a free Samoa.
He posted a series of photos from celebration events on his official Twitter page yesterday, saying: "A privilege to represent New Zealand at Samoa's 55th Independence Day anniversary celebrations. Soifua!''
Later, he posted a video of Samoan Prime Minister Tuilaepa showing off his musical skills; with a guitar in hand and singing along with a band.
Clearly impressed, Engish said: "Samoa's Prime Minister raises the bar for Prime Ministers everywhere.''
