Groups campaigning for the rights of Britons living abroad are encouraging citizens to write to their UK constituency MP to ask them to back the Votes for Life bill.
The second reading of a Private Member's Bill, which is being led by Glyn Davies, Conservative MP for Montgomeryshire, is due to be heard in the House of Commons on Friday 23 February.
While Private Members' Bills do not generally form part of planned UK government legislation, Votes For Life, which would scrap the current law that UK citizens who have lived outside the country for more than 15 years do not have the right to vote in UK elections, has been part of the Conservative Party's manifesto for the last two election campaigns (2010 and 2015). However, they have failed to act on the pledge.
Ninety-six-year-old World War II veteran, Harry Schindler, who lives in Italy, is well-known across Europe for his long-running campaign to get the law changed and has been an active voice in the current mobilisation.
