OK so he might be focusing on islands specifically off the coast of Britain, but they're not too far away from our shores and we do like Mr. Clunes (as do the commissioners; he's been getting an extraordinary amount of  work recently). This new three-part series sees the Reggie Perrin star travel from the most northern tip of Britain to the southerly seas as he visits some of the 1,000 culturally diverse islands around the mainland. Beginning in the Shetlands, Martin's first port of call is Muckle Flugga, a lighthouse rock which is the wildest and most northerly tip of Britain, where the Atlantic and North Seas meet. Ferocious storms have claimed the lives of numerous sea farers, and it was touch and go whether the weather would allow Martin to travel to the island.
