HC Deb 23 May 1966 vol 729 c30W
Mr. Berry

asked the Secretary of State for the Home Department in what circumstances policemen take over the control of traffic at Hyde Park Corner.

Mr. Taverne

The Commissioner of Police informs me that police officers take over control of traffic at points of entry into and exit from the Hyde Park Corner roundabout when congestion begins to build up or when an accident or other emergency requires their intervention.
