"This is about redefining the relationship between benefit claimants and the state. The welfare state will support people when they fall on hard times, but in return they need to meet some contracted responsibilities agreed with a Jobcentre Plus adviser.
"It's a fair deal people will have to sign up to in return for receiving support from the state. Our reforms are ushering in a new culture of conditionality and the Claimant Commitment lies at the heart of this," he said.

People claiming Universal Credit will need to sign the Claimant Commitment, explaining how they will go about finding work or "additional or better paid work" if already in employment, to receive the benefit.
