Former Thai prime minister Srettha Thavisin, who was vocal in his support for the LGBTQ community during his time in office, has tweeted his congratulations, saying "equal marriage has truly become possible with the power of all".

Srettha's Pheu Thai party, which still leads the ruling coaliton, pushed for marriage equality - but the bill also had broad support, clearing parliament last year with a thumping majority.

"From now on, there will no longer be a 'man' and a 'woman', but 'individual' and 'individual' who are equal 'spouses,'" he said in a post on X.

"I congratulate you wholeheartedly on your love."

Actors Apiwat Apiwatsayree and Sappanyoo Panatkool, who held an unofficial wedding ceremony two weeks ago, are among the couples getting their union recognised today.

Apiwat, widely known as Porsch, starred as Dr Bright in the popular series Together with Me and its sequel.

Sappanyoo, also known as Arm, is known for his role in the 2023 series Ai Long Nhai: The Endless Love.

Both shows are part of the "Boys Love" genre - romcoms and dramas about relationships between men.

As we've been reporting, dozens of couples are now getting married at the luxury Siam Paragon mall.

It may seem like a strange choice of place, but its central location means it's easy for people to get to.

It also provides a large, air conditioned exhibition hall that can host big events like concerts and expos.

Also, Thailand is a hot place and often humid. So Thais are used to spending a lot of their time in the malls on the weekends and holidays.

Besides Siam Paragon, hundreds of couples are also expected to flock to district offices across Bangkok to get their marriage certificates.
