Judging by the net changes in support for the three principal UK-wide parties, support for the 'others' - including the SNP, Plaid Cymru, Greens, UKIP and BNP - appears to be up a full three points in the latest YouGov poll released tonight. That might (or might not) bode well for the SNP's showing in the Scottish sub-sample, which on past form should be published tomorrow. The UK-wide figures that have been released so far are -
Conservatives 41% (-3)
Labour 31% (-1)
Liberal Democrats 15% (+1)
And as ever, the wait for the detailed figures from the ICM poll published earlier this week is proving lengthy.
