反独裁民主戦線
After the coup d'état in Thailand 2006, she became a supporter of the United Front for Democracy Against Dictatorship ("Red Shirts"). During the protests of 2010, she belonged to the more moderate wing of the movement and was concerned to see the militant tendencies within the group. Her commitment to the "Red Shirts" and the political polarisation in Thailand led to a decline of donations for her "Duang Prateep Foundation" from within the country. Some regular donors who are affiliated with the opposite political camp refused to give to an organisation headed by a "Red Shirt" and stopped their payments.
