"Citizens of the European Union who are not Commonwealth citizens can vote in European and local elections in the UK, but are not able to vote in UK Parliamentary general elections"It says resident here:
or an Irish, qualifying Commonwealth or European Union citizen who is resident in the UK.
Anyway, bushy is right. It is ridiculous that Johnny Foreigner should be allowed to vote in our parliamentary elections, especially if there is no reciprocal arrangement. Utterly ridiculous.
