My constituent Alexandra Mitchell is unable to walk without heavy metal callipers. She cannot use her feet to drive and has hand controls in the Motability car she now stands to lose because her PIP assessment says that if she can drive, she must be able to walk. Does the Minister accept that this example, and those we have heard from other hon. Members, calls into question the quality of PIP assessments? Does she accept that the system is flawed and needs to be sorted?
