HC Deb 04 June 1985 vol 80 c137W
Mr. Boyes

asked the Secretary of State for Foreign and Commonwealth Affairs what technology is used in the hot line between Britain and the Union of Soviet Socialist Republics.

Mr. Luce

The technology used enables the exchange of printed messages in the language of the originator over cable or radio channels which are directly and continuously available between the two capitals.

Mr. Boyes

asked the Secretary of State for Foreign and Commonwealth Affairs, pursuant to paragraph 116 of the defence Estimates, whether the hot line between Britain and the Union of Soviet Socialist Republics(a) requires modernisation,(b) is proof against the electromagnetic pulse generated by a number of kiloton range nuclear explosions in central and northern Europe and (c) is regularly tested.

Mr. Luce

(a) In its present form the hot line is adequate for the exchange of printed messages for which purpose it was established. The scope for use of other systems is constantly under review; (b) No; (c) Yes.
