20,000 people have turned out in Belfast city centre to call for the legalisation of same-sex marriage in Northern Ireland, according to Amnesty International.
The march, organised by Amnesty, the Irish Congress of Trade Unions and the Rainbow Project, began at the Ulster University at York Street at 2.30pm and ended with speeches outside City Hall.
The Northern Ireland campaign for the introduction of same-sex marriage has been buoyed by the success of the recent referendum in the Republic - and by a wave of celebrity endorsements from the world of sport, music and theatre.
The province is now set to be the only part of the UK or Ireland where civil marriage is denied to gay couples.
Unionists have rejected four Sinn Fein motions calling on the Executive to legislate for marriage equality.
Celebrity supporters of the campaign include Olympic boxer Paddy Barnes, singers Brian Kennedy, Gary Lightbody and Bronagh Gallagher and actress Nuala McKeever.
