A poll everyone missed?

Yesterday's Sunday People had a new YouGov poll that, as far as I can tell, everybody missed. The topline figures, with changes from YouGov's last poll, were CON 40%(-2), LAB 25%(nc), LDEM 20%(+2), Others 16%. It was conducted between the 21st and 23rd July, so was finished prior to the Norwich North result and any halo effect the Conservatives enjoy on the back of it.

Labour and the Conservatives are at the same sort of level as we've seen in recent YouGov polling, but it's worth noting that 20% figure for the Liberal Democrats. It's the highest YouGov have had them since September last year (though before you get too excited, the monthly YouGov poll for the Telegraph should be along this week, so let's see if that confirms it).
