Elections: Compulsory voting on UK polling days?

Voting in the UK is optional, and turnout has continued to fall, especially in local and European elections.

However in some countries voting is compulsory, with the threat of a fine for those who fail to take part.

Adam Fleming took the mood box - an unscientific test with plastic balls - to see if people thought such an approach should be introduced in British elections.

More mood box films from 2013, 2012, 2011 and 2010.
