Ex-customs manager warns on 'hard' Brexit border

Sean Kelleher, the man responsible for overseeing customs enforcement on the Irish border for eight years, has warned the Irish Revenue and Customs service is not adequately resourced to deal with a hard Brexit.

Mr Kelleher monitored the 310-mile frontier from Carlingford Lough in the east to Lough Foyle in the west.

BBC News NI spent a day with him to discuss his concerns.
