Accra - Former central bank governor Kwesi Bekoe Amissah-Arthur was on Monday sworn in as Ghana's new vice president after his nomination was approved by parliament.
The 61-year-old banker was chosen by new President John Mahama who succeeded John Atta Mills following his sudden death on24 July.
Ghana's chief justice Georgina Theodora Wood administered the oath of office to Amissah-Arthur at a colourful ceremony in parliament attended by senior government officials and party supporters.
The new vice president expressed gratitude to Ghanaians for having confidence in him and promised not to disappoint them.
"I want to express my gratitude to all those who have supported me during my nomination and approval by the parliament of Ghana," he said.
He promised to work with the president in the interests of the nation.
Mahama, who had been vice president, was sworn in to serve out the remainder of Mills's term, as dictated by the west African nation's constitution.
Ghana will hold a state funeral service and burial for Mills between Wednesday and Friday.
The late leader died five months ahead of presidential elections, in which he was to seek re-election.
Presidential elections are to be held in December in the country seen as a bastion of democracy in the often turbulent region.
