Protesters last night performed a Chinese war drums battle cry amid rising anger in Thailand at the country's recent sham election.

Footage shows the demonstration at the Ratchaprasong Intersection, in the centre of the Thai capital opposite the CentralWorld shopping mall, where activists wore black shirts and unfurled banners across walkways.

Disenfranchised voters across Thailand have begun demonstrating in recent weeks following the bizarre national poll on May 15, in which winner Pita Limjaroenrat of the progressive Move Forward Party was blocked by the army from becoming Prime Minister.

Military and monarchy powers who retain control of the country said Pita's winning manifesto to water down benighted Lese Majeste laws were a 'threat to national security'. He also angered big business with plans to break up monopolies.

In a double-whammy to any hopes of democracy in the developing country, Pita was also suspended and is facing up to 10 years in jail and a 20-year ban from politics over shares held by his late father in an inactive media company.
