Erin writing in her EasyExpat.com blog on 4th May, has provided a good overview of our on-going campaign to remove the 15-year-limit on the rights of British overseas citizens to vote in UK national elections.

Votes for Expat Brits blog 
I agree with Mr Shindler and wish him good luck. Losing the right to vote in the UK because of the time limit was painful. Various countries have different rules about voting depending on nationality and on residence, which means that some people can vote in 2 or more countries, some nowhere. I feel that this situation needs to be sorted out internationally.
