Anti-government protesters have vowed to stage larger rallies in central Bangkok and push ahead with plans to nullify the results of national elections.

Protest leaders called Monday on supporters to "keep fighting" and consolidate crowds in the capital's business district, a day after national elections marred by protests and the closure of thousands of polling stations.

The elections were peaceful and were able to proceed in 90 percent of constituencies but the disruptions mean that political limbo will continue for weeks or months, until new by-elections can be held.

The struggle to hold the vote was part of a 3-month-old conflict that has split the country between supporters and protesters of Prime Minister Yingluck Shinawatra.

Demonstrators have occupied major intersections and forced government ministries to shut down and work elsewhere.
