A senior member of the political party accused of orchestrating demonstrations in Paraguay that left at least two people dead, has promised to launch more protests against President Luis Gonzalez Macchi.

Macchi blamed the now exiled former General Lino Oviedo for violence

Luis Villamayor's UNACE party was founded by Lino Oviedo, who is now in self-imposed exile in Brazil after being accused of masterminding several coup attempts.

Mr Villamayor denied government allegations that UNACE organised this week's demonstrations, but told me that it would now stage a populist street campaign to oust the president.

"The party will do that now officially, through all the legal means that we have, not because we decide or because Oviedo decides.

"It's because our people are hungry and we absolutely don't have another choice and cannot wait one or two more days."

More protests expected

There is plenty of confusion in Paraguay in the wake of the violent wave of protests that erupted on Monday.

Nobody is sure who instigated the trouble. Questions are being raised about the government's handling of the state of emergency, declared by the president.

And it is not clear how the government plans to worm its way out of the economic crisis that brought people onto the streets in the first place.

But what is clear is that this country has not seen the last of the protests.

The government expects it and now one opposition bloc has promised it.

Belarmino Balbuena, who heads one of the country's two largest peasant organisations, said they were not involved in the clashes but that they are now planning their own street campaign.

The president of the Senate, Juan Carlos Galaverno, is convinced that the opposition is actively trying to destabilise the country by inciting trouble and he expects more violence to come.
