Contributing to a UK personal pension is legal for up to 5 years after you leave the UK (I think you must have the pension started before you leave).
I don't think the question is which govenment will dare to reduce the value of the state pension. The question is where is the money going to come from?
From memory (so the numbers may not be quite correct), I think the gist of the problem is that currently there are about 3 people working and paying tax for every pensioner. In 30 years time there is likely to be approximately 1 for 1 (due to the ageing population). So who will pay all for all the pensioners?
OK so we will probably end up retiring aged 70, and the UK will skimp on the health budget to save money, but still things don't add up.
My feeling is that they will gradually means-test the state pension, like they did with eye care/dental/retirement homes etc.
