Is the oil Scottish or Shetland? I have yet to meet a Shetlander who feels he is Scottish their roots are more Scandinavian than Scottish. The island was mortgaged to James III by King Christian I of Norway in 1469. James III then annexed (stole) the island in 1472.
If Salmond offers the Scots a referendum on independence from UK then surely he must offer Shetland a chance to be independent from Scotland or remain with UK - see how much oil he has then!!
