Mr Portman, who plays a peace-loving squire on the show, also argued that a Brexit could lead to increased tensions on the continent and in the UK.

A so-called Brexit would give a boost to "the far-Right's politics of intolerance", he warned.

Author Val McDermid, who announced last month that she was backing a Remain vote, said that Scottish culture had long benefited from "sharing our creativity with our neighbours and developing strong links with European institutions, going back to the Middle Ages.

"Our culture has become richer, wider and deeper as a result."

The group admit that the EU is not perfect.
