On June 17, 2025, reporters revealed that Prime Minister Paetongtarn Shinawatra informed Bhumjaithai Party leader Anutin Charnvirakul of a potential Cabinet reshuffle. The proposed changes would exchange the Ministry of Interior portfolio, currently held by Bhumjaithai, for the Ministry of Public Health, along with an additional ministerial position at the Ministry of Commerce.

In response, Anutin reaffirmed his intent to remain in his current position and declared his readiness to move into the opposition if necessary. This has raised widespread speculation about the stability of the current coalition government should a compromise between the Pheu Thai and Bhumjaithai parties not be reached.

As of June, the House of Representatives has 495 active MPs, requiring 248 members for a quorum. If Bhumjaithai were to join the opposition, the coalition government would immediately lose 71 MPs—69 from Bhumjaithai and 2 from the Thai Sang Thai Party’s Udon Thani MPs who have aligned with Bhumjaithai.

This would reduce the government bloc to 261 MPs, including:

  1. Pheu Thai Party – 142 MPs
  2. United Thai Nation Party – 36 MPs
  3. Kla Tham Party – 26 MPs
  4. Five "cobra" MPs (who crossed party lines): Krit Cheewathamanan (People's Party), Kanjana Jangwa (Palang Pracharath), Thakorn Thantasit (party-list), Rampoon Tantivanichanon (Ubon Ratchathani), Supaporn Salabsri (Thai Sang Thai)
  5. Democrat Party – 25 MPs
  6. Chartthaipattana Party – 10 MPs
  7. Prachachat Party – 9 MPs
  8. Chartpattana Party – 3 MPs
  9. Thai Ruam Palang Party – 2 MPs
  10. Seri Ruam Thai Party – 1 MP
  11. New Democracy Party – 1 MP
  12. Thai Kao Na Party – 1 MP

Meanwhile, the opposition would grow to 234 MPs, led by:

  1. People's Party – 142 MPs
  2. Bhumjaithai Party – 69 MPs
  3. Two Udon Thani MPs from Thai Sang Thai
  4. Palang Pracharath Party – 19 MPs
  5. Thai Sang Thai Party – 1 MP
  6. Pen Tham Party – 1 MP

This shift in parliamentary balance underscores the fragile nature of the current coalition and highlights the significant impact that Bhumjaithai’s potential move to the opposition could have.
