Nattawut joined the National Development Party in 2001 and moved to the Thai Rak Thai Party of Prime Minister Thaksin Shinawatra in 2005. Inside TRT, he formed a faction together with his "buddies" and political allies Jatuporn Prompan and Veera Musikapong. After the overthrow of Thaksin and the forced dissolution of TRT, he represented the People's Power Party in the 2007 Thai elections. He became Deputy Spokesman for the Samak Sundaravej government on February 6, 2008. On October 7, 2008, he became the spokesman for the Somchai Wongsawat government. Nattawut, alongside Jatuporn and Veera, is one of the leaders of the United Front of Democracy Against Dictatorship, colloquially called the "Red Shirts". The UDD is a political pressure group that campaigned and fiercely protested against the 2006 Thai coup d'état, which overthrew the government of Thaksin Shinawatra, against the military-installed government and the government of Abhisit Vejjajiva. Nattawut and his friends had a role in the initiation of the pro-Thaksin People's Television channel. Moreover, they hosted the political talkshow Truth Today. Nattawut co-organised the mass protests in 2009 and, together with the other UDD heads, led the "Red Shirts" in the fierce protests from March to May 2010 that led to the bloody military crackdowns of April and May. Nattawut, Jatuporn Prompan and other Red-Shirt leaders surrendered themselves to police to prevent further bloodshed during the violent military crackdown on 19 May 2010. Afterwards, Nattawut was prosecuted on terrorism charges. He was released on bail terms on 22 February 2011. At the 2011 Thai general election Nattawut Saikua was elected Member of Parliament on the winning Pheu ThaiParty list. When Prime Minister Yingluck Shinawatra reshuffled her cabinet on 18 January 2012, Nattawut was named Deputy Minister of Agriculture and Cooperatives. After the Cabinet reshuffle on 28 October 2012, he changed to the Ministry of Commerce. He lost his government office during the coup d'état on 22 May 2014. After the coup, he was held in military detention for seven days, alongside other "Red Shirt" leaders.
Controversies
In a 2010 speech, Nattawut insinuated that Jarungjit Thikara, a lady-in-waiting of Queen Sirikit, ordered the army to crack down on the 2010 protests on the queen's behalf. On 22 June 2013, a music video surfaced on YouTube featuring Nattawut singing about and promoting local grocery stores. The video received harsh criticism, with some viewers stating it was a waste of government spending.
