Peter Kellner on #wato: A week ago, Corbyn was comfortably ahead. Now, I donâ€™t know

We don’t know whether what Kellner said is based on data
There’s been an easing of the Corbyn price on the Betfair exchange after the above comment by YouGov president, Peter Kellner, in an interview.
At one stage this morning he was at 1.35 on Betfair. That is now 1.43.
Kellner clearly sees a lot more polling and other data than is made public and my guess is that his comment on the World at One was not taken out of the air but is based on something.
