First post-Glasgow poll

Populus have carried out an extra snap poll following the Glasgow East by-election, it was conducted between the 25th and 27th, so is the first with fieldwork conducted entirely after the by-election result.

The topline voting intention figures are CON 43%(+2), LAB 27%(-1), LDEM 18%(+1), so a slight shift to the Conservatives, but that's taken from a poll that had a much lower Conservative lead than that shown by other pollsters. From this it doesn't look that Glasgow East has been able to further damage Labour's popularity, though the speculation since then can't be doing them any favours - not that we'll really be able to tell now, since we are heading into the August bank holidays when we tend to be a bit suspicious of polls given the effect summer holidays may have on sampling.
