Sri Lanka's former military chief has officially announced he will challenge President Mahinda Rajapaksa in the country's presidential elections on January 26.

General Sarath Fonseka said Sunday in the capital, Colombo that he will run as a common candidate of opposition parties. He oversaw the military operations that ended 25 years of civil war between the government and Tamil Tiger rebels.

The two main opposition parties have said they will support General Fonseka, who resigned from the military earlier this month after accusing the president of sidelining him and falsely suspecting him of plotting a coup.

Analysts say President Rajapaksa called for early elections in hopes of capitalizing on his popularity following the defeat of the rebels in May.
