Singapore to repeal law that criminalises sex between men

For years, campaigners have repeatedly challenged section 377A in the courts, but have been unsuccessful.

The groups also expressed disappointment that Lee said he intended to change the constitution to prevent future legal challenges to the existing definition of marriage.

Religious groups, however, have voiced opposition to change, and have said this could lead to further calls for equal marriage.

Section 377, a legacy of colonial rule, continues to exist in some form in many countries across Asia, including in south-east Asia countries such as Malaysia, Myanmar and Brunei.

Across Asia, only Taiwan has legally recognised same sex marriage.
