Scottish independence: Davidson on Cameron 'Tory toff' David Cameron admitted his "appeal did not stretch to every single part" of Scotland when asked about a debate over the independence referendum. MPs laughed as Ian Davidson said he wanted to "agree" with the prime minister against SNP calls for the PM to debate with Alex Salmond, and that a debate should be between the leaders of the yes and no campaigns. The Labour MP said the "last person" that pro-union Scots would to represent them would be a "Tory toff from the Home Counties, even one with a fine haircut."
