BANGKOK - Thai "red shirt" protesters threatened on Tuesday to march on an army barracks where Prime Minister Abhisit Vejjajiva has been based after the Election Commission unexpectedly recommended his party be dissolved.

Abhisit, who came to power in 2008 when the army brokered a deal in parliament, would have to step down if the Constitutional Court, following the Election Commission's findings, found his Democrat Party guilty of funding irregularities.

The red shirts, who want Abhisit to quit now, said they would step up their protest, after their month-long rally turned violent on Saturday, with plans to send out hundreds of motorcyclists handing out leaflets and pictures from the clashes.
