As we approach the end of 2020, we’ve been asking Newstalk listeners what the 20 most influential moments of the last 20 years are… We had the first Black President of the United States, the Queen in Croke Park, a new currency, Brexit, a pandemic… Over the next few weeks, we’re focusing on one of the Top 20 each day – and today we focused on 2015's Marriage Equality referendum. Tánaiste Leo Varadkar speaks to Andrea Gilligan about why he chose to come out publicly in the lead-up to the referendum. Tom Dunne revisits the views of Roscommon, the only constituency to vote 'No' in the referendum. Colm O'Gorman and Tiernan Brady look at how Ireland compares to other countries around the world when it comes to same sex rights. Shane Coleman catches up with Gráinne Healy, chair of Marriage Equality and co-director of the Together for Yes campaign. And Kieran Cuddihy hears from Senator David Norris, a longtime campaigner for gay rights.
