David Maddox: The Numbers Game (17)

I've just been handed the odds by one of the SNP's government special advisors (spin doctors) from Ladbrokes on the likelihood of the SNP reaching various targets.

It would be wrong to assume that this has anything to do with the First Minister's well known favourite past time outside eating curries, but no doubt he has taken a punt.

Alex Salmond's target of 20 seats for the SNP is 15/8 with the bookies, but I think a brave punter might look at the generous 9/1 for 26 to 30 seats.

The European election result would have given the SNP 27 or 28 seats in theory, if Electoral Calaculus is to be believed, and I must admit that my own calculation based on the MP expenses scandal fallout and some narrow margins of error could see the SNP win as much as 29 seats.

Here are the odds:

0-5 Seats 33/1

6-10 Seats 8/1

11-15 Seats 2/1

16-20 Seats 15/8

21-25 Seats 4/1

26-30 Seats 9/1

31+ Seats 12/1
