Tony Benn said that in politics there are two types of strategies: signposts and weather vanes. Progressive parties should be signposts not weather vanes, he said.
On the issue Brexit, however, the Labour Party’s position is like that of a weather vane, reacting to the popular opinion found in constituencies that traditionally vote Labour.
But many of the arguments in favour of Brexit are based entirely on false assumptions. The role of a signpost is to point out misconceptions and expose them for what they are.
