asked the Postmaster General whether it was with his authority that letters containing vague threats were despatched to right hon. and hon. Members, who had signed Early Day Motion No. 328, in franked envelopes of his Department from the Richmond and Twickenham Post Office at 5.15 p.m. on 16th June; and what action he proposes to take.

No. The use of official envelopes for sending communications of this nature was completely unauthorised. If we could trace the offender serious disciplinary action would be taken.
