As Britain goes to the polls today to elect a new government, there's one group of people who won't be voting - the country's prison inmates.

Along with several other European countries, including Luxembourg, the Czech Republic and Bulgaria, the UK doesn't allow sentenced prisoners to vote. Following a campaign by former inmate John Hirst, the European Court of Human Rights in Strasbourg ruled in 2004 that the law was breach of the European Human Rights Convention, but the British government still hasn't lifted the ban.

Other Brits denied the vote include the royal family and hereditary peers in the House of Lords.
