Recognised as a major influence on the thinking of a future Conservative government, the Policy Exchange is moving beyond Freud to look at one of the enduring problems of the welfare state: the ever-increasing complexity of benefit rules, and how they might be simplified. As Theresa May acknowledged in her own appearance at the conference, research on this is in the earliest stages, and the session was mostly a debate rather than a presentation of results. Taking the idea of a single, universal benefit as a starting point, the discussion quickly revealed why so many ministers have come in intending to simplify the benefits system and left with something even more complex in its place.
