The control of access to the House of Commons is vested in you, Mr Speaker, and not the Commission. Mr Speaker announced additional access restrictions on Monday 16 March, following the statement by the Prime Minister to prevent the risk of exposure to coronavirus. This includes restricting access to passholders and to those attending for business reasons, such as witnesses to Committees. Those measures were implemented with immediate effect. Updates on Tuesday and yesterday outline further measures to prevent the risk of exposure to covid-19, including stopping all non-essential access to the estate, and from today closure of several search and screen points around the estate.
