The Tory reshuffle is recognition that Purnell has shot the Tory fox on welfare reform

James Purnell can take great satisfaction from the Tory reshuffle today. The decision to replace Chris Grayling as shadow DWP with Theresa May shows that the Tories do not think that there is much political advantage to be gained on welfare reform now. If the Tories were planning to make this a major dividing line in the election they would have appointed a policy heavyweight like Nick Herbert or an energetic media performer like Jeremy Hunt.
