We have the Liberal Democrats arguing for yet another referendum on the European Union and now we have the Scottish National Party pushing yet again for another referendum on independence for Scotland. Less than three years ago they held a referendum on exactly that proposition and we were told it would settle the issue for a generation. Constantly pushing for independence for Scotland is of course the whole reason for the existence of the Scottish National Party. I think the Prime Minister was quite right yesterday to make it clear that until we have left the European Union there will be no second referendum.
