Mozambique's ruling Frelimo party has elected Daniel Chapo, a regional governor, as its new leader, positioning him as the leading candidate to succeed President Filipe Nyusi later this year.

Chapo's appointment follows heated debates within the party over the weekend, during which his main competitor withdrew from the race.

The choice of Chapo, a former political science lecturer and radio personality, comes as a surprise given his lack of previous cabinet experience.

The constitution bars President Nyusi from seeking a third term when elections are held on October 9.

Since Mozambique gained independence from Portugal in 1975, Frelimo has never been defeated in elections.
