Unauthorised crossings of the Border, including inadvertent ones, have always been viewed by the Government as a very serious matter. The Deputy can be assured that all incursions by British security forces personnel into this jurisdiction are immediately raised with the British authorities through the Anglo-Irish Secretariat in Belfast.
I instructed that the Border incursion by a British Army helicopter on 13 March be raised through the Anglo-Irish Secretariat. On this occasion, as previously, the British side were apprised of our strong concerns.
In response the British authorities have indicated that the incursion occurred due to navigational error. They have conveyed their apologies.
