My meeting with Sir William Lawrence, chairman of Tourism For All, is proving problematic. As he emerges from a meeting at the Local Government Association (LGA) in Westminster's Smith Square, a pint at the nearby Marquis of Granby is out of the question as his wheelchair doesn't fit through the door. A moment of calm at St John's Church opposite Local Government House is also impossible, given the numerous steep steps and lack of a ramp.

Instead we head for a coffee in the LGA's first-floor café. That is, of course, having first negotiated the lift, a simple enough manoeuvre but one that entails fellow lift users side-stepping the wheelchair, trying to hold the doors open for us and mumbled apologies as we all try to squeeze into the confined space.
