Thailand's embattled premier Abhisit Vejjajiva said Thursday the lower house of parliament will be dissolved in September, paving the way for November polls in a bid to end a crippling political crisis.

Thailand's anti-government "Red Shirts", who have been waging a campaign of protests to force snap elections, have signed up to Abhisit's reconciliation "roadmap" which envisages holding national polls on November 14.
