Work and Pensions Secretary says "we will keep the policy under review" when asked whether the cap could be reduced from £26,000.
As Andrew Adonis argues, successful reforms are incremental and build on existing best-practice, rather than trying to reinvent the wheel.
More bad news for Duncan Smith as the National Audit Office says there are "considerable weaknesses" in the department's financial controls over the programme.
The Work and Pensions Secretary says he "never wanted to dwell on figures" after the OBR forecasts less than 10% of his original target will be met.
On the day of George Osborne's Autumn Statement, the Work and Pensions Secretary finally admits that he will miss his Universal Credit deadline of 2017.
