Burundi's former main Hutu rebel group, which won recent parliamentary elections, has nominated leader Pierre Nkurunziza to be the next president.
Pierre Nkurunziza (l) was a PE lecturer
Burundi's new leader will be chosen by the National Assembly - in which the FDD has a majority - and by the Senate.
Mr Nkurunziza said he was confident of winning and has resigned as head of the FDD, in compliance with election rules.
The moves are part of a deal to end a 12-year war between rebels from the Hutu majority and the Tutsi-led army.
"There are no reasons for fear, we are sure to win the [Assembly] election on 19 [August]," said Mr Nkurunziza.
The 41-year old is a former university lecturer and is said to be a deeply religious man.
International election observers praised the peaceful polls and the defeated parties accepted the results.
The defeated ruling Frodebu party has indicated they will not contest the presidency next month.
The biggest challenge for the Forces for the Defence of Democracy (FDD) will be to bring the only remaining rebel group, the FNL into the peace process, observers say.
