I'm too posh to fight for Scotland, concedes 'Tory toff' Cameron The Prime Minister has refused to take part, saying the debate must be held between Scots and that Alistair Darling, the leader of the "No" campaign and Labour MP for Edinburgh South West, should debate Salmond instead. At Prime Minister's Questions, Ian Davidson, Labour MP for Glasgow South West and an opponent of independence, said: "Without seeking to give offence to the Prime Minister, could I tell him that the last thing Scots who support the No campaign want to have as their representative is a Tory toff from the Home Counties, even one with a fine haircut." Mr Cameron laughed heartily and said: "I humbly accept that while I am sure there are many people in Scotland who would like to hear me talk about this issue, my appeal doesn't stretch to every single part." The reason the Yes campaign head and the No campaign head can't seem to get a debate is those who want to break up the United Kingdom are losing the argument and want to change the question. He earlier said there was "mounting frustration" in the SNP at the state of the separation campaign. Support for independence has remained stubbornly low at around 30 per cent over the last year. Some 61 per cent of Scots want to remain part of the UK, according to YouGov polling this week. But the Conservatives poll comparatively poorly in Scotland, holding one seat in Westminster, 15 out of 129 seats in the Scottish Parliament and 116 out of 1,220 council seats. Some 'No' strategists fear that the working class men, particularly in the West of Scotland, could hold the balance of power and vote for independence in order to punish the Government.
