I would urge anyone with a vote to vote in favour of this treaty. It is the people of the candidate countries who matter; it is people we are talking about bringing into the European Union, not just states. It brings to mind the words of Yeats in that marvellous poem we all read in school, Easter 1916: "Too long a sacrifice can make stone of the heart." These countries have had five grim decades of making sacrifices. They have made sacrifices of another sort in order to gain membership of the EU, and let us not disappoint them now.
