I thank my hon. Friend for his question. He reminds me to pay tribute, too, to the retiring Serjeant at Arms, who is a very distinguished figure. He is also absolutely right to raise the matter that he does. Blind and severely visually impaired people clearly face significant challenges in living independent lives. Up until April 2011, the disability living allowance failed to reflect those challenges. The Government have put in place changes to rectify this, and I encourage him to seek an Adjournment debate, so that he can raise this particular concern directly with the appropriate Minister, but I will also pass on his concern after today’s proceedings.
