HC Deb 22 November 1916 vol 87 c1426
55. Mr. GILBERT

asked whether three police constables have been dismissed from the Metropolitan Police Force, because they had joined the National Union of Police and Prison Officers; and if the Chief Commissioner has issued an order that no officer or constable of the Metropolitan force may join this union or attend any of its meetings?

Mr. SAMUEL

The answer to both questions is in the affirmative. The number, however, is four.
