Thailand is set to become the first Southeast Asian nation to recognise equal marriage after politicians passed a same-sex marriage bill. The lower house of parliament overwhelmingly voted in favour of the bill, with 400 supporting its passage and just 10 against it in a final reading on Wednesday. Should the bill take effect, Thailand would be just the third Asian country to legalise gay marriage. The bill now requires approval from the country’s Senate, and finally endorsement from the king, before becoming law. More than a decade in the making, the legislation could take effect within 120 days of royal approval.
