AFP - Bolivian President Evo Morales, seeking reelection in weekend elections, said Tuesday the law would be changed so a conservative opposition candidate and his running mate could be jailed for corruption.

"We are going to change the law and the two of them can go to jail," said Morales, running for a second term in Sunday's elections.

He was referring to both Manfred Reyes Villas, who is under investigation for corruption while in office in Cochabamba, and his running mate Leopoldo Fernandez who was detained a year ago in a La Paz jail.

Morales, the socialist incumbent, said the two were "thieves who steal the people's money."

The former coca leaf growers union leader Morales is positioned to be comfortably reelected to a second term in Sunday's presidential vote, a new poll showed Monday.

He stands to receive some 55 percent of the vote, according to an Ipsos-Apoyo survey of 2,980 people published in La Razon newspaper.

Morales was elected to his first term in office in 2005 and is the first indigenous Bolivian elected president in a majority indigenous nation.

He is trailed by his right-wing opponents, economist and businessman Samuel Doria Media and Reyes Villa, a former soldier and governor of Cochabamba, who polled at 10 percent and 18 percent respectively in the survey.
