I come back to the uncertainty. On clause 5 on social security co-ordination, 80% of the British living in Europe are of working age or below. That is an awful lot of people potentially affected by social security aggregation, and add to that the pension issues that Jeremy has already outlined. We are talking more than 1 million people who are affected by social security aggregation—the aggregation of the contributions they make to their retirement pension. That is a fundamental right that we all moved across the Channel with.
I would also add that British citizens moving abroad are mobile. It is not so much that a British citizen moves from the UK to one country. We are mobile citizens, and many people have worked in three or four different countries. That is a complicated aggregation scenario. It is entirely possible, due to the rules in individual countries about minimum contribution periods—in Italy, you have to contribute for 20 years before you can receive a pension; in the UK, as you know, it is 10; in France, it is 10; and so on—that without co-ordination, people could work an entire working life and not receive any state pension.
