Economics, education and the move from evidence to policy

Sirikanya Tansakun was born in Chon Buri on 4 April 1981. She completed lower secondary school at Chonkanyanukoon School before moving to Triam Udom Suksa School in Bangkok. At Thammasat University she studied economics, joined student activities and encountered Thanathorn Juangroongruangkit through a rural development camp. She later earned a Thammasat master’s in economics and a Master of Economics, Markets and Organizations from Toulouse School of Economics in France.

Her early career was built around applied research rather than electoral politics. Sirikanya worked at the Thailand Development Research Institute in 2011–2012, then managed research at Thailand Future Foundation from 2012 to 2016 and served as a senior consultant at The Advisor. She later explained that policy research could be ignored when it conflicted with political incentives. Entering politics offered a way to argue for implementation rather than only publish recommendations.

Future Forward policy director and first election

Future Forward recruited Sirikanya as policy director in 2018. The new party combined opposition to continued military rule with proposals on decentralisation, competition, welfare, labour rights and reform of the armed forces. Her job was to turn broad political commitments into costed and defensible programmes, making technical economic communication part of a campaign aimed especially at younger and urban voters.

The party won 81 seats in the March 2019 election, and Sirikanya entered the House through its party list. She became chair of the Economic Development Committee, using hearings and parliamentary debate to examine budgets, public borrowing, market concentration and the economic response to COVID-19. The role established her public reputation as a legislator who challenged ministers with figures and institutional detail rather than relying primarily on political rhetoric.

Dissolution and economic leadership in Move Forward

The Constitutional Court dissolved Future Forward in February 2020 over loans from Thanathorn and imposed ten-year bans on sixteen executives. Sirikanya was not among the banned executive group, so she joined most surviving MPs in Move Forward and became a deputy leader responsible for policy. The succession preserved parliamentary work while reinforcing a central problem for the reform movement: winning votes did not guarantee that the party organisation itself would survive legal challenge.

During the Prayut Chan-o-cha government, Sirikanya became a leading opposition voice on pandemic spending, energy prices, public debt and the annual budget. Her criticism was not limited to demanding more expenditure. She repeatedly asked how programmes were targeted, whether fiscal commitments were transparent and whether concentrated industries prevented households and smaller firms from sharing economic gains. That combination of redistribution and structural competition shaped Move Forward’s later economic platform.

The 2023 victory and a government that never formed

Move Forward won 151 of 500 seats in May 2023, finishing first ahead of Pheu Thai. Sirikanya returned as a party-list MP and was widely identified with the party’s proposed finance team. She defended plans to break monopolies, reform taxation and welfare, decentralise public spending and improve the productivity of smaller businesses. Critics questioned the feasibility and pace of those reforms, placing her at the centre of the argument over whether the election winner could translate a reform manifesto into government.

Pita Limjaroenrat’s eight-party alliance controlled 313 House seats, but the post-coup Senate still participated in choosing the prime minister. Pita fell short in the July vote, and Pheu Thai later formed a different coalition that excluded Move Forward. Sirikanya therefore remained in opposition, scrutinising the Srettha administration’s digital-wallet programme, fiscal assumptions and institutional relationship with the Bank of Thailand rather than taking the cabinet role supporters had anticipated.

From Move Forward to the People’s Party

On 7 August 2024, the Constitutional Court dissolved Move Forward because of its campaign to amend Penal Code Article 112 and banned eleven executives for ten years. Sirikanya was a deputy leader but was not on the executive board covered by the ruling, a distinction that allowed her to keep her House seat and continue party work. Two days later, the remaining MPs regrouped in the People’s Party under Natthaphong Ruengpanyawut.

Sirikanya became deputy leader for policy. Reports had treated her as a possible successor to the party leadership, but she said Natthaphong was the only nominee and that she had put his name forward. Her continued role illustrated both organisational continuity and legal adaptation: Future Forward, Move Forward and the People’s Party were separate legal entities, but personnel, policy expertise and many voters carried the reform project across each dissolution.

A 2026 prime-ministerial candidate and state-reform agenda

For the February 2026 election, the People’s Party named Sirikanya as one of three prime-ministerial candidates and placed her second on its national list. The party won 120 seats and became the largest opposition bloc; official party records list her among the party-list MPs of the twenty-seventh House. The result returned her to parliament for a third consecutive term even though Bhumjaithai and Pheu Thai formed the governing coalition.

The People’s Party launched a shadow cabinet in April with Sirikanya leading state reform. Its agenda linked budget decentralisation, regulatory simplification, public data, anti-corruption safeguards and administrative capacity. That assignment broadened her public identity beyond the label of party economist. By late 2026, her significance lay in combining research training, budget scrutiny and institutional reform while remaining one of the most senior women in Thailand’s parliamentary opposition.
