LA PAZ - With broader popular support, Evo Morales won relatively easy Suncay's elections and clinched a second term as Bolivia's President.

Morales, Bolivia's first ever indigenous President, was re-elected with between 61 percent and 62 percent of the vote as exit polls suggest, securing a convincing victory on Sunday's elections thus avoiding a run-off with his conservative rivals.

His main opponent Manfred Reyes Villa, a former governor, stayed well behind with about 23 percent, exit polls indicate while the official results are expected in the coming days.

His other challenger was Samuel Doria Medina, a wealthy businessman.

Foreign observers have praised the election for its transparency and fairness.

Jubilant supporters waving Bolivian flags jumped up and down in La Paz's central Murillo square an hour after polls closed chanting "Evo! Evo!".

The leader of the Movement towards Socialism (MAS) had promised to expand state control over the economy and redistribute profits from the gas industry if re-elected, among other pledges to boost the Gross Domestic Product and the social welfare.

Political analysts have suggested that the landslide victory will solidify Morales' dominance in Bolivian politics and weaken the split conservative opposition tied to the business elite.

On his final campaign rally, Morales told a cheering crowd: "There are two roads: continue with change or return to the past".

Earlier surveys had predicted He would also likely gain control of Congress in one of South America's most troubled and poorest countries.
