Political career
Sanoh has an influential trucking business, his home district being located near an important checkpoint at the Thai-Cambodian border. Sanoh entered politics with the Thai Nation Party in 1975. One year later, he was elected to parliament representing Prachinburi Province which at the time still contained today's Sa Kaeo Province. From 1986 to 1988, he was Deputy Minister of Agriculture and, for a short phase of less than two months in 1992, Deputy Minister of Transport. When Banharn Silpa-archa became leader of the Thai Nation Party in 1994, he made Sanoh secretary-general. The following year, Banharn became Prime Minister and called up Sanoh to the government, appointing him Minister of Public Health. In 1996, Sanoh resigned from the Thai Nation Party and joined the New Aspiration Party of Chavalit Yongchaiyudh, and immediately took up the position of secretary-general. After Chavalit had won the election and become Prime Minister, he made Sanoh Minister of the Interior. As a minister, Sanoh Thienthong is said to have coined the term Ya ba instead of "Ya ma" for the mix of methamphetamine and caffeine which used to be prevalent in Thailand. For the election in 2001, he changed to the Thai Rak Thai Party of Thaksin Shinawatra. Sanoh was made chief adviser of the party. He was not given a government office, but his wife Uraiwan was appointed minister. Alternately, she led the Ministries of Culture and Labour. Inside the Thai Rak Thai Party, Sanoh led a faction called the "Wang Nam Yen group", named after Sanoh's home district. In 2004, around 70 MPs, mainly from the Northeastern region were affiliated with this group. After discord with Thaksin, Sanoh Thienthong left TRT on 25 February 2006. After Thaksin had dissolved the parliament, Sanoh spoke at several rallies of the People's Alliance for Democracy, an anti-Thaksin pressure group. He formed a new party, called Pracharaj Party. Sanoh became leader of the party which declared political reform and the removal of the Thaksin regime as its aims. On 13 May 2011, he abandoned his Pracharaj Party to join the Pheu Thai Party. He supported the top candidature of Yingluck Shinawatra and on 5 August, it was Sanoh who proposed her election as Prime Minister to the parliament. Sanoh Thienthong, who has the reputation of a behind-the-scenes powerbroker and king-maker, has been dubbed "Godfather of Wang Nam Yen", or "Godfather of the eastern border"
