Ipsos MORI/Standard - CON 40, LAB 29, LDEM 14, UKIP 9, GRN 3

Ipsos MORI's monthly political monitor is out in today's Evening Standard. Topline voting intention figures with changes from last month are CON 40%(-2), LAB 29%(-4), LDEM 14%(+4), UKIP 9%(+2), GRN 3%(nc). The 14 point score for the Liberal Democrats is the highest MORI have recorded for five years.

So far we have had three polls since the Richmond Park by-election and while ICM and YouGov did not have the Lib Dems doing as quite well as MORI, all three have shown them improving, suggesting they have received a boost from their by-election victory and the publicity it gave them. Whether that leads to any lasting recovery, or fades away again once the by-election is forgotten, is a different question.
