Here is a link for any ex-pats living here less than fifteen years who would like to register to vote in the UK Referendum (or the next General Election) https://www.gov.uk/register-to-vote

I didn't register to vote in the last UK GE and I wish that I had.  I will certainly be voting on this.  The rest of my life will be affected by the way that this vote goes and I'm not going to sit on the sidelines and just watch.
