Morales, 59, who swept to power in 2006 as the country's first indigenous leader, hailed the official result of Sunday's vote as another historic triumph for his leftist movement and accused the opposition, without evidence, of trying to stage a coup d'etat with foreign backing.

Morales faced a fifth day of street protests in La Paz and other cities that begun after an official quick count of votes was suddenly suspended on Sunday when it revealed Morales heading to a riskier run-off election against rival Carlos Mesa.

A confident Morales said then his socialist party MAS would get an outright win as rural votes trickled in.

The tabulation of ballots at 100 per cent on Friday confirmed his prediction, giving him a 10.57-point lead over Mesa, less than a point above what he needed to avoid a second-round vote.

Election monitors, the opposition and some foreign governments criticised the election for lacking transparency.

The European Union, the United States, Brazil, Argentina and Colombia called for Bolivia to convene a second-round vote to ease the unrest.

Brazil's foreign ministry said it would not recognise Morales' win while an audit of the vote count by the regional group Organization of American States (OAS) was still pending.

The only countries that have congratulated Morales on his win were Venezuela, Cuba and Mexico.

After nightfall, Bolivians banged on pots and pans in a traditional form of protest. Earlier, roads were blocked and demonstrators surrounded the headquarters of the country's electoral board, guarded by rows of police in anti-riot gear.
