Universal credit is solving some serious problems in the benefits system. It is helping people to move into work more quickly and, together with the national living wage, is helping to drive down unemployment. The Minister is right to take a cautious approach to rolling out universal credit but, further to the question from Kate Green, can he assure me that he will move as quickly as possible to introduce regulations that solve the problem for people on severe disability premium? I have a constituent whose disabled son has lost money because he has moved local authority. It is obviously an indefensible situation. He will want to fix it. Can he assure me that we will move quickly to solve this problem?
