It is very difficult to get the people of our country to agree about anything. So much divides us in the UK. The gap between north and south, rich and poor, the various stratas of the class system. At regular intervals the politicians agonise about what it means to be British. But we don't even know if our country will survive a referendum in Scotland. National disunity - that is our distinguishing feature, as in the old Likely Lads sketch where Terry Collier goes through a list of all the people he loathes, starting with southerners, and ends up by concluding that he hates the bloke who lives next door.
