Due to the ongoing protests in London today (24 April 2019), the Police have put in place barriers in Parliament Square to create a clear route for access (either as a pedestrian or in a vehicle) to the Parliamentary Estate.
Police will be on hand at the barriers to check passes. In order to prevent delays, visitors who are due to attend events/tours/select committees in Parliament today will be asked to show evidence to prove this.
However there may still be delays in gaining access to Parliament today so please arrive earlier than planned if at all possible.
