The BBC and the three main UK parties agreed to hold pre-election TV debates of their leaders while excluding leaders of all the other parties including the Scottish National Party, Plaid Cymru and the UK Independence Party.
BBC: SNP and Plaid threaten legal action over TV debates
Not only I agree that such a format would (will?) give an unfair advantage to the three main parties and that inviting Clegg but not Salmond is anticipating the outcome of the election. I also agree that such debates overemphasize the leaders in the context of a voting system in which one is supposed to vote for a local MP rather than for his party leader.
