The Government will today apologise to gay people who were convicted because of their sexuality before the decriminalisation of homosexuality in Ireland 25 years ago.
An all-party motion will acknowledge the hurt and harm the law prior to 1993 caused to gay people, their family and friends.
Labour Senator Ged Nash tabled the motion, which is expected to get the support of the Cabinet at its meeting this morning.
Later the Taoiseach Leo Varadkar is set to deliver a key speech in the Dáil.
Politicians from across the Dáil and Seanad will also speak on the motion.
The apology comes ahead of a Government reception in Dublin Castle next weekend to mark the 25th anniversary of decriminalisation.
