The Tartan Curtain is a term of reference to the change in status of the Scottish border with England in the event that Scotland becomes an independent sovereign state, as supported by the Scottish National Party. It has also been used colloquially to refer to more general differences in policy between Scotland and England due to Scottish devolution. The term has been used in parliament, the press and in public discussions associated with Scottish Independence. It carries the negative connotations of the Iron Curtain which divided Europe during the Cold War.
