After their summer break Lord Ashcroft’s weekly GB poll start up again today with topline figures of CON 28%, LAB 35%, LDEM 8%, UKIP 18%, GRN 6%. Tabs are here.

Meanwhile this morning’s twice weekly Populus poll has topline figures of CON 34%, LAB 36%, LDEM 9%, UKIP 12%, GRN 4%. Tabs are here.

Later on tonight there is also a TNS Scottish poll due to be published, so we shall see if the sharp narrowing in YouGov’s recent polling is echoed or not.
