A debate between possible prime ministers is a very different thing than a debate including leaders of smaller parties. I see very little way of sensibly dealing with the different geographic footprint of UK political parties. In 2010 we objected because the SNP weren’t included in a debate; in 2015 a debate included the SNP and Plaid and the English Greens, but not the Scottish Greens. And a consistent dearth of Northern Irish parties. And I’m never happy about the prominence that the broadcasters give to UKIP, considering how limited their Westminster presence has been.

Anyway, I feel we get much more from a detailed one-on-one interview with a party leader; the Today programme, or perhaps Andrew Neil.
