My Lords, it was a pleasure to discuss the issue of M4(2) with the noble Baroness and the noble Baroness, Lady Brinton, last week. The Government strongly support the rights of disabled people. This is important and we are behind local authorities which are keen to take this forward. I agree that it is for building companies to respond to that; they have a responsibility. We have an ageing population as well as people with disabilities. It is the mark of a civilised society as well as a point of self-interest, quite honestly, that we should do these things. On both those bases, the Government are solidly behind what the noble Baroness is saying.
