Votes referendum: Cameron and Clegg set out views
Prime Minister David Cameron and his deputy Nick Clegg have both made speeches on how the UK elects its MPs - from opposite sides of the debate.
If the public votes for change in the 5 May referendum it will mean an end to Britain's traditional first-past-the-post system, which would be replaced by the Alternative Vote (AV).
Both stressed they would work together regardless of the result - the PM said it was not a "coalition breaker".
