I am grateful to the hon. Gentleman. We have, of course, focused very seriously on disabled visitors to the visitor centre. We have provided for their assistance; we have provided facilities; and we have even provided disabled parking. We have provided training for staff to assist disabled visitors, and we have looked at the visitor route as a whole to assess its accessibility. I think that the Commission, on behalf of the House, can say that it has gone a great way towards meeting the demands of the disabled. We are always ready to improve and to listen to suggestions, and we are all trying at every moment of the day to increase these facilities.
