evidence: Rockall is an island which covers about half the area of an ice-hockey rink, sitting 260 miles (418km) west of Scotland’s Western Isles. It was thrust into the headlines earlier this month when the Scottish Government warned that vessels from the Republic of Ireland could be boarded if they fish within 12 miles (19km) of the rock formation. [...] But Irish Prime Minister Leo Varadkar told his parliament earlier this month: "Rockall is a rock, essentially a sea stack in the middle of the ocean. It’s uninhabitable, uninhabited and I don’t think it is something that Ireland and Scotland should fight over. We don’t have a claim on it. We don’t accept any other sovereign claim on it." [...] Indeed, amid the Scottish-Irish dispute, Iceland also fired its own shot across the bows of the Rockall standoff. Last week, the small Nordic island reaffirmed its national claim by declaring that "the Hatton-Rockall area is part of the Icelandic continental shelf".
