Anthony Wells of UKPolling Report emails me to tell me that he has asked Populus to disclose the poll referred to by Benedict Brogan in his blog.

He wrote” “Tories say privately their internal Populus poll paints a completely different picture – the parties are level pegging and Mr Cameron’s approval rating is climbing”.

Anthony’s view is that there is a requirement to disclose under the British Polling Council’s transparency rules.

Normally leaks of “private polls” don’t name the pollster. I’m writing this on my phone in a Eurotunnel train and am not in a position to support Anthony.

It will be interesting to see what transpires.
