Thailand was locked in political stalemate on Sunday with demonstrators planning a fresh protest with their own blood after refusing talks offered by the government. <br/> <br/>Buoyed by a huge parade, the defiant "Red Shirts" said they would paint their blood on a white canvas, left over from the gallons they have splattered on the prime minister's house and offices during their week-long protests. <br/> <br/>The noisy carnival-like convoy in Bangkok on Saturday by the mainly rural supporters of ousted premier Thaksin Shinawatra aimed to recruit urban support and revive the so-far peaceful rally, which had begun to wane. <br/> <br/>Earlier, Prime Minister Abhisit Vejjajiva said the demonstrators had agreed to meet one of his ministers. <br/> <br/>But upon returning to their main rally site, after waving flags and honking horns in a bid to win over Bangkok residents, the Red Shirts stuck to their demands for snap elections.<br/><br/>
