An important issue for many of us is what will happen to expatriot pension rights, such as retaining the right to free health care and continuing to receive regular pension increases, when the UK withdraws from Europe.
Currently there are 2 petitions before parliament to preserve these rights which can be found here.
[You must be registered and logged in to see this link.]I don't know exactly what rights a British expat is entitled to, such as winter heating allowance etc., because it will be 16 years before I reach state pension age but the ones that are in place should be preserved.
Sorry to bleat on about petitions again, but they are not well advertised and without the information you can't make the choice.
