But there is more to it than this. Purnell has long argued it is time to discard the old tropes of Brownite and Blairite.

And if Purnell has been talked about on the right of the party, then Jon Cruddas can be broadly defined as on the left. Cruddas is known to be in a quandary about how to respond to the Hotmail plot. However, in the last year, Cruddas has been very complimentary about Purnell – regarding him to be a Blairite the left could be able to do business with.
