Bolivia’s President Evo Morales has said he will call a new election after international monitors questioned the validity of his victory last month.
The Organization of American States (OAS), which monitored the elections, called for the result to be annulled.
Morales’s announcement comes after weeks of anti-government protests over reported irregularities and fraud.
The president, who was first elected in 2006, has denied any wrongdoing and ignored calls to resign.
In his announcement on Sunday, he also said the country’s electoral body would be overhauled before the poll, with parliament choosing its members.
