Patrick Hillery's two-term presidency is often dismissed as largely uneventful - he played golf, travelled the world on state visits and flew under the radar on home affairs.

But in this episode of Think You Know...The Presidents?, Lise Hand and Flor Mac Carthy find just the opposite.

Did you know that Hillery was forced to deal with scurrilous rumours of an extramarital affair at a time when the Pope was visiting Ireland?

Or that he was embroiled in political controversy when senior members of Fianna Fáil made calls to Áras an Uachtaráin to try and persuade the president not to dissolve the Dáil?
