A search has been launched amid reports of a Russian submarine being spotted off the north of Scotland.
An RAF plane, Royal Navy Frigate and submarine are all believed to be involved in the search, alongside French maritime patrol aircraft, with the Telegraph reporting that the French plane has been searching for the submarine for at least 10 days.
