them to communicate directly with the government on the challenges island communities face in terms of levelling up. Flag Roy Grönneberg, who founded the local chapter of the Scottish National Party in 1966, designed the flag of Shetland in cooperation with Bill Adams to mark the 500th anniversary of the transfer of the islands from Norway to Scotland. The colours are identical to those of the flag of Scotland, but are shaped in the Nordic cross. After several unsuccessful attempts, including a plebiscite in 1985, the Lord Lyon King of Arms approved it as the official flag of Shetland in 2005. Local culture and the arts After the islands were officially transferred from Norway to Scotland in 1472, several Scots families from the Scottish Lowlands emigrated to Shetland in the 16th and 17th centuries. Studies of the genetic makeup of the islands' population, however, indicate that Shetlanders are just under half Scandinavian in origin, and sizeable amounts of Scandinavian ancestry, both patrilineal and matrilineal, have been reported in Orkney (55%) and Shetland (68%). This combination is reflected in many aspects of local life. For example, almost every place name in use can be traced back to the Vikings. The Lerwick Up Helly Aa is one of several fire festivals held in Shetland annually in the middle of winter, starting on the last Tuesday of January. The festival is just over 100 years old in its present, highly organised form. Originally held to break up the long nights of winter and mark the end of Yule, the festival has become one celebrating the isles' heritage and includes a procession of men dressed as Vikings and the burning of a replica longship. Shetland also competes in the biennial International Island Games, which it hosted in 2005. The cuisine of Shetland is based on locally produced lamb, beef and seafood, some of it organic. The real ale-producing Valhalla Brewery is the most northerly in Britain. The Shetland Black is a variety of blue potato with a dark skin and indigo-coloured flesh markings. Language The Norn language was a form of Old Norse spoken in the Northern Isles, and continued to be spoken until the 18th century. It was gradually replaced in Shetland by an insular dialect of Scots, known as Shetlandic, which is in turn being replaced by Scottish English. Although Norn was spoken for hundreds of years, it is now extinct and
