反独裁民主戦線
In 2009 Chaturon joined the United Front for Democracy Against Dictatorship (UDD), also known as the "Red Shirts" movement. Reportedly, Thaksin wanted Chaturon to become one of the movement's leaders, but he could not come out on top, given the network's heterogenous and decentral structure. Still, Chaturon supported the "Red Shirts" during their protests in 2010. He condemned the violent strategy of Abhisit Vejjajiva's violent approach toward the protest movement, but also insisted that the "Red Shirts" should keep a non-violent strategy, arguing against hardcore leaders of the movement.
