Today’s YouGov is based on fieldwork which started on Tuesday evening and finished late after yesterday – so would have covered the Mili-Mail flare-up and Dave’s big speech yesterday.
The latest shares are CON 34, LAB 40, LD 9, UKIP 10. So the two main parties had 74% between them which is a very high proportion compared with other recent polling. It looks like the LDs and Ukip have been squeezed by the parties which had their conferences at the end of the cycle.
Generally we need to wait a couple of weeks before we can start to say what overall impact the conferences and other biggest recent events have had.
