Disputed island lies deep in the Atlantic, 187 miles west of Scottish island of St Kilda
An expedition is to be launched this summer to reclaim the tiny island of Rockall for the UK.
Adventurer Andy Strangeway has been given permission by the Government to fix a plaque on the island, ownership of which is disputed by the UK, Ireland, Faroe Islands and Iceland.
Royal Navy personnel from the survey ship HMS Vidal were landed on the island by helicopter in 1955, but the plaque they left cemented in place has since disappeared.
Mr Strangeway, who hopes to mount his expedition in June or July, said that landing on Rockall was a hazardous venture.
“Even in calm conditions it can be impossible,” he said, “it is very dangerous.”
