I imagine that you might end up with different social security treaties being negotiated with different countries. There are not always arrangements with other countries to uprate pensions, for instance, whereas with the EU, at least until now, it has been the case. I suppose some treaties would cover that and some would not. It makes a big difference over time to pensioners who are not getting their British pensions uprated. Again, that might be something you want to address in the legislation, to specifically require pensions to be uprated, for instance.
