Sorry if this has been discussed before but as outsider looking in with will Labour and the SNPs go into coalition if the numbers work out. Lib Dems should be irrelelevent and it is not inconceivable that the tories will have say 315-320 seats, Labour on roughly 280, SNP on around 45 guaranteed. The bookies aren't giving odds on Labour SNP though so I presume it is out of the question which is madness considering they would be the two most compatible parties to provide a good coalition government.
