The UK Government has opened a site containing e-petitions. If over 100,000 signatures are obtained, the e-petition could be debated in the House of Commons.
Currently, http://epetitions.direct.gov.uk/petitions/16387 takes you directly to the END THE UNFAIR FROZEN OVERSEAS PENSION POLICY petition - as long as you are a British Citizen you may sign the petition. Closing date is 08/09/2012.
Add your signatures, and we may get another opportunity to change this silliness, as why should it be different for Brits in the U.S. (for example).
Best regards,
Diane
