HC Deb 26 March 1964 vol 692 c184W
Commander Kerans

asked the Minister of Public Building and Works if he will state on what dates the clocks in the Chamber of the House of Commons last stopped.

Mr. Sharples

The clocks last stopped on 19th March, 1964; the fault was corrected and the clocks were restarted after about 45 minutes. This is believed to be the only occasion on which the system has failed since it was installed in 1950.
