asked the Secretary of State for the Home Department if he will call for a report from the Commissioner of Police of the Metropolis as to the number of police officers who were used to keep order during the Trades Union Congress mass meeting in London on Sunday 9 March; and what was the cost to public funds of the police operation during this meeting.

I understand from the Commissioner that a total of 1,814 police officers were on duty. The cost of the policing arrangements has been estimated as at least £144,000.
