[11] He was living in Hamilton, staying with a middle-class host family, at the same time as future New Zealand Prime Minister Jacinda Ardern, with whom he would later attend Harvard University.

[13] After completing his secondary education in New Zealand, Pita returned to Thailand and enrolled in Thammasat University, where he pursued a bachelor's degree in finance at the Faculty of Commerce and Accountancy.

However, Thaksin, who had written Pita's recommendation letter for Harvard,[21] was unable to deliver his speech due to a military coup on 19 September, leading to his departure for London.

[23] At the age of 25, Pita returned to Thailand to take over as managing director of CEO Agrifood, a rice bran oil business run by his family, after the death of his father.

This theory highlighted the need for government focus on key agricultural policies, including land ownership, farmers' debts, cannabis, agro-tourism, and water resources.

[45] On 22 May, Pita and his coalition partners held a press conference, where they focused on key issues such as drafting a new constitution through the constituent assembly, implementing military reforms, introducing voluntary conscription, legalizing same-sex marriage, and decentralizing the economy.

[49] On 9 June, the Election Commission (EC) dismissed three complaints against Pita concerning his ownership of iTV, a television broadcaster and a unit of Shin Corporation, previously owned by Thaksin Shinawatra, a former Thai Prime Minister now in exile.

According to Pita, the company hadn't produced significant media-related income for years, except for minor earnings from a subsidiary involved in broadcasting equipment rental.

[57] On 12 July, the Constitutional Court said it had accepted a complaint against Pita and the Move Forward Party by the Election Commission, that said its plan to reform lèse-majesté laws amounted to an attempt to "overthrow the democratic regime of government with the king as a head of state".

[61] Despite securing a majority-coalition in the lower house, Pita was unable to win enough votes from the assembly in the first ballot, particularly the 250 members of the Senate, appointed by the National Council for Peace and Order (NCPO) in May 2019, to become the country's next prime minister.

[81][82][83][79] At a public speaking event held more than a year later at the University of Melbourne, Pita said he that he actually had a plan to "lobby the upper house" to allow him to become prime minister before he was suspended from parliamentary duties.

- Pita Limjaroenrat[93] On 22 August, Pheu Thai candidate Srettha Thavisin won the 2nd prime ministership election in the National Assembly of Thailand.

[101][102] He cited his inability to perform duties in the House, pending a ruling regarding his suspension status as an MP in the Constitutional Court, hindering his ability to become the Leader of the Opposition.

Pita announced a total of 47 draft bills set to be introduced into the legislature, which included policies for military reforms, quality of life, and rural development.

[137][138] On 5 February, in another separate case, Pita and seven other progressive politicians were given four-month suspended prison sentences from the Pathum Wan Municipal District Court in Bangkok, over an unlawful rally that was held in December 2019.

[154] Move Forward was not physically present at the court for the verdict, opting to watch from a conference room at the Parliament building; Pita and Chaithawat arrived at around 1:50 PM, and were once again swarmed by reporters.

[149] After 43 minutes, the court ruled that Move Forward's campaign promise to amend the lèse majesté was unlawful and tantamount to attempting to overthrow the monarchy, and ordered the party to cease related activities.

[157] Pita believed the case damaged free speech and the health of Thai democracy, while Chaithawat stated the ruling changed the definition of a constitutional monarchy.

CNA described the ruling as a “gag order”, and reported that some Move Forward MPs believed it would just be a matter of time before a petition would be filed to dissolve the party.

[204] Pita believes Thailand will break out of its “vicious cycle” of protests and coups, taking inspiration from successful democratic transformations in South Korea and Indonesia.

[207] In an April 2024 interview, Pita said Pheu Thai and Move Forward were “aligned” in their goal to review and reform the country's lèse-majesté (royal insult) laws before the election, but that changed shortly before the Srettha government was sworn in.

[120] Pita supports legislation that would regulate air quality and require companies to register chemicals transported around the country, as a means of mitigating the effects of climate change.

[213] He described the detention of former prime minister Thaksin Shinawatra as political persecution, while also believing his treatment was evidence of double standards in Thailand's justice system.

[163] During a 2024 climate change summit in Malaysia, Pita accused the current government of working too slowly to fight global warming by giving a small budget to relevant agencies and setting unambitious environmental goals.

[163] Celebrating the 190 anniversary of American-Thai relations, Pita stated he “trusts the US - Thai alliance.”[225] He supports expanding the U.S.-Thai alliance beyond defense to include the environment, trade, infrastructure and the digital economy.

[28] In June 2023, Pita said he would support and help organize ASEAN-led peace efforts in Myanmar, amidst a humanitarian crisis that has been ongoing since the country entered a civil war in 2021.

[231] In an interview with CNA, Pita said he was inspired by Prime Minister Lee Kuan Yew of Singapore, and has compared politics to a marathon rather than a sprint, saying "I have the stamina to run for a long time.

[235] In a June 2024 interview with the Melbourne Asia Review, Pita stated "My favorite leader in the world who I look up to is Jacinda Ardern," the Prime Minister of New Zealand from 2017 to 2023.

[21] In December 2023, it was reported that Pita had inadvertently leaked the tracklist of the debut album of K-pop group Babymonster, when he posted photos from inside YG Entertainment studios on Instagram during a trip to South Korea.

[259] According to results from a National Institute of Development Administration (NIDA) poll survey, published at the end of 2023, Pita remained the most popular politician in Thailand, trumping Srettha Thavisin as the preferred prime minister.
