Votes referendum: PM David Cameron's speech in full

David Cameron sets out his views in support of the existing first-past-the-post system, as campaigning ahead of the 5 May referendum on electoral reform gets going in earnest.

The prime minister believes that the current system for electing MPs provides decisive results and accountability.

The government pledged to hold a vote on the issue in its coalition deal.
