Bolivia elections: Concern as results transmission pauses

Preliminary results suggest Evo Morales will face his rival in a run-off

There is concern in Bolivia after the electoral authority stopped updating its website showing the preliminary results of the presidential election.

With almost 83.8% of votes verified, incumbent President Evo Morales led with 45.3%, leaving his main rival, Carlos Mesa, in second place with 38.2%.

The partial results suggest Mr Morales does not have the votes needed to win outright and will have to face Mr Mesa in a second round.

The run-off is scheduled for December.

What happened?

The site showing the preliminary results stopped being updated at 83.8% of the votes at 19:40 local time (23:40 GMT) on Sunday,

Supreme Electoral Tribunal President María Eugenia Choque said there could not be two sets of results

The failure to update the results caused immediate concern not just with opposition politicians but also with the regional body Organisation of American States (OAS) which has election observers in Bolivia.

The OAS tweeted in Spanish that it was crucial for Bolivia's Supreme Electoral Tribunal to explain why the transmission had been interrupted.

Tribunal president María Eugenia Choque said it had stopped the transmission of the preliminary results because the regional tribunals had started announcing the official results. "We can't have two sets of results at the same time," she said.

However, the official results have not yet been released.

What has the reaction been?

Mr Mesa said the interruption in the transmission of the results was "extremely serious".

"We're not going to allow the manipulation of a result that obviously puts us in a second round," Mr Mesa said in a video he published on Twitter (in Spanish).

Before the transmission was halted, Mr Mesa declared that he had achieved "an unquestionable victory which allows us to say with certainty that we've made it into a second round".

President Morales told cheering supporters he was confident that when votes from rural areas were counted there would be no need for a run-off.

"The rural areas are going to keep guaranteeing this process of change," he said.

"That's why, sisters and brothers, we're going to wait until the last vote is counted to pursue and continue our process of change."

Why is the delay a problem?

Mr Morales is a divisive figure, praised for his social policies but criticised for challenging presidential term limits. He has won all his previous terms in the first round and so the prospect of this election going into a second round suggests he is losing support.

These were the most uncertain elections for Mr Morales, with many people angry with his insistence on running again, our correspondent Katy Watson in La Paz reports.

In a referendum in 2016, Bolivians rejected his suggestion to ditch the presidential term limits.

But his Movement for Socialism (Mas) party took the matter to the constitutional court, which ruled in the president's favour, allowing him to stand for a fourth term.

In order to win outright, a candidate needs 40% with a 10-percentage-point lead over his nearest rival or more than 50% of the vote

Mr Morales has been in power since 2006 and if he wins another term, he will be in power until 2025.

No trust in the system

The halting of the vote count will play into the hands of Evo Morales critics who forewarned of foul play in these elections.

It is true that the rural votes, when they come in, are likely to go in Mr Morales' favour but to be so sure of triumph before all the votes are in, to his critics does not just smack of arrogance but of fishy politics.

The problem is, since Mr Morales lost the 2016 referendum on term limits and carried on regardless, people no longer trust the system and an explanation probably will not calm nerves.

These next few weeks ahead of a supposed second round are unlikely to be straightforward.

What was the election fought on?

President Morales has been widely praised for growing the Bolivian economy and, at the same time, cutting extreme poverty.

But he has been criticised over his environmental policies, after forest fires that destroyed four million hectares of land in eastern Bolivia.

Many question whether a decree passed by the president, which quadrupled the amount of land farmers are allowed to clear for agricultural production, contributed to the blazes.

Many indigenous Bolivians continue to back him, saying Mr Mesa - who is running for the Civic Community (Comunidad Ciudadana) political alliance - embodies the white Bolivian elite and question his commitment to the poor.

In the election campaign, Mr Mesa argued that with oil and gas revenue declining, Bolivia needed to be "more sensible and rational" in the way it spent its money, especially as the country had a fiscal deficit of 7.8% of GDP.

But his message of curtailing spending has not proven popular with poor voters who have seen steady improvements to their quality of life under President Morales.
