Absentee voting in the United Kingdom is allowed by proxy or post (known as postal voting on demand) for any elector. Proxy voting is allowed for people who will be away, working, or medically disabled. Anyone eligible to vote in the election may be a proxy for close relatives and two unrelated people. Postal voting does not require a reason, apart from in Northern Ireland, where postal voting is available only if it would be unreasonable to expect a voter to go to a polling station on polling day as a result of employment, disability or education restrictions.Pilots in 2003 and 2004 showed a significant increase in turnout where postal voting was trialled and no evidence of an increase in electoral fraud. However, a 2016 government report found postal voting to be vulnerable to "fraud, undue influence, theft and tampering." (en)
