evidence: Rockall dispute: why Scotland and Ireland are fighting over the tiny island [...] Rockall gives its name to one of the 31 weather areas around the British Isles, familiar from the Shipping Forecast programme on BBC Radio 4. [...] The Irish government has never claimed sovereignty of the islet but does not acknowledge the UK’s right to exclude Irish fishermen from the waters nearby. According to the BBC, the Rockall fishery is "a multimillion pound" business, with several species of fish including haddock, monkfish and squid inhabiting the waters.
