Mr. Leslie Huckfield
asked the Minister of Posts and Telecommunications what is the current percentage connection failure rate estimated by the Post Office on subscriber trunk dialling.
Mr. Chataway
The Post Office Report and Accounts showed the percentage of calls ineffective due to the system as 8·7 per cent. in 1970–71. I am told that the current rate is about 1 per cent. lower.
