Mozambique's top judicial body has declared Armando Guebuza the country's new president, after rejecting an opposition challenge to last month's vote.
The chairman of the Constitutional Council, Rui Baltazar, spoke at a public ceremony Thursday, saying voting problems did not affect the final outcome.
Earlier this week, the Council rejected a legal challenge to the election, saying opposition Renamo leaders had filed late.
The opposition had alleged ballot fraud in the December poll, saying thousands of votes in some areas were not counted.
Mr. Guebuza is set to be inaugurated February 2 to succeed President Joaquim Chissano, who is retiring.
