A recent report published by the Commission on Digital Democracy stated that, by 2020, secure online voting should be an option for all voters in the UK.
The recommendation is based on a November 2014 report by the House of Commons Political and Constitutional Reform Committee that urged the Government to run pilots in the next Parliament elections.
The Royal London Society for Blind People has also called for online voting to be introduced in time for the 2020 election.
Voter turnout in the UK is very low. Compared to the post-1945 elections of the 20th century, the average turnout in general elections this century has dropped by 14 points to 62%.
The picture is even worse when looking at the less high-profile elections. The average voter turnouts for the London Mayor, Welsh Assembly, Local Council, and European Parliament elections, are all less than 50%. The turnout in the 2012 Police and Crime Commissioner elections was only 15%.
Although there are other issues influencing voter participation, such as trust in politicians, education, and the policies of political parties, evidence suggest that online voting would increase turnout.
In a recent survey, 71% of respondents said they would be more likely to vote if they could do so online. This is particularly the case amongst young people. Also, in a study of youth engagement, it was found that 66% of young people would be more likely to vote if they could do so online.
