If Rishi Sunak really is going to revisit the definition of value for money as benefiting areas that already had high property prices, then good luck to him. The last Labour Government certainly never did that. Nor would the present Labour Leadership.
That Leadership is either going to whip an abstention, as is its wont, or it is going to vote with the large number of Conservative rebels that there would be over this. It is impossible to imagine anything more divisive of the Conservative Party as it now existed.
