People's Alliance for Democracy
Santi was appointed a Privy Councillor of King Bhumibol Adulyadej in 2005. During the height of protests against Prime Minister Thaksin Shinawatra, General Suchinda Kraprayoon (head of the 1992 coup) suggested that Santi was the best possible mediator between Thaksin and the People's Alliance for Democracy. He died while holding that position in 2011.
