Nick Harvey: Improvements in access to the Parliamentary Estate for people with disabilities have been ongoing for many years. A Disability Access Audit Report was produced in April 2004 which set out the then current situation and recommended a continuing programme of improvements. Notable recent projects have included installation of ramps, such as in Star Chamber Court; installation or modification of lifts and the installation of hearing loops in Committee Rooms. There is an ongoing programme of work to improve lifts in and around the Parliamentary Estate to aid access for people with disabilities and access audits have been commissioned for each building comprising the Parliamentary Estate.
