Patrick Kielty: One Hundred Years Of Union

BBC1, 9pm

It's 100 years since the creation of Northern Ireland, and 23 since the Good Friday Agreement, but Brexit and protests over the summer have led to fears that old conflicts are resurfacing. Kielty (above) looks at how his native Northern Ireland's past problems might shape its future and speaks to people who were born after the ceasefire. ★★★★★
