Allow British citizens living abroad to vote at an Embassy

British citizens living abroad are often denied their right to vote on matters affecting them. This occurs as postal votes frequently fail to arrive, and if they arrive at all, votes typically have insufficient time to return to the UK. British citizens living abroad should have the right to vote in, or return a postal vote to, an embassy in their country of residence. This is an option offered in many other countries and would allow those living abroad to have a voice.
