Apology: The actual YouGov numbers did not show an increase in the Tory lead. Instead, they showed the Tories unchanged at 39 and Labour unchanged on 33. Apologies.
The second poll of the night is much better for the Tories and will calm some jangled nerves. A YouGov poll carried out for the Sun after the Rawnsley revelations and has the Tories up two to 41 with Labour dropping four to 29. This poll has, obviously, been taken at the worst time for Labour but, at first blush, it does suggest that the bullying allegations have cut through.
