Chartthaipattana Party

The Chartthaipattana Party (CTPP; Thai: พรรคชาติไทยพัฒนา, lit. 'Thai Nation Development Party') is a conservative Thai political party. It was founded on 18 April 2008 in anticipation of the 2 December 2008 Constitutional Court ruling which dissolved the Thai Nation Party and banned its executive members from participating in politics for five years beginning on that date. Numerous former members of the Thai Nation Party joined the Chartthaipattana Party, therefore, the party is considered its de facto successor.

The party has a strong base in Suphan Buri Province. The first party's leader was Chumpol Silpa-archa, the younger brother of former Prime Minister Banharn Silpa-archa, who has been banned from politics by the Constitutional Court. On 15 December 2008, the party joined the Democrat Party, forming a six-party coalition government under Abhisit Vejjajiva. In Abhisit's cabinet, the CP supplied the Deputy Prime Minister (Sanan Kachornprasart), the ministers of Tourism and Sports (Chumpol Silpa-archa), and Agriculture, and the deputy minister of transport.

For the general election on 3 July 2011, Chartthaipattana forged an alliance with coalition partner Bhumjaithai Party. The party's target was to win at least 30–35 seats and it was even hopeful that it could, as the third party, propose a "reconciliation prime minister". Eventually, the CP won 19 of the 500 seats in the house of representatives.

The party joined the Pheu Thai Party-led coalition government under Prime Minister Yingluck Shinawatra in 2011.

The party elected Kanchana Silpa-archa, daughter of former prime minister Banharn Silpa-archa, to lead them in the 2019 election. On 10 October 2022, the younger son of Banharn Silpa-archa, Varawut Silpa-archa, became the Leader of the Party following the resignation of his sister. Varawut Silpa-archa had been speculated to become the Leader back in 2018.
