The Government dismissed claims it had deliberately obstructed an inquiry into the botched roll out of their flagship Universal Credit reforms.
A spokesman for the Department of Work and Pensions said:
Universal Credit and its IT systems are very clearly working well, with claimants receiving the new benefit and moving into work.
We deliberately started in a slow, controlled and safe way, which the Committee itself has long recommended, so we can expand Universal Credit securely to more people.
Universal Credit is on track and we will start expanding it to other Jobcentres from this summer.
We have made our plans to roll out Universal Credit very clear with regular updates.
