Bad Days at Cheltenham

The old boys wrestle with another spy scandal

The headquarters of Britain's electronic intelligence empire is a sprawling compound at Cheltenham, 95 miles northwest of London and nestled among the scenic hills of Gloucestershire. Known in the trade as GCHQ (for Government Communications Headquarters), the facility receives and analyzes data from a worldwide system of spy bases, ships, planes and satellites. It operates round the clock and employs some 10,000 staffers round the globe. Cheltenham is a vital part of the West's constant effort to break the Soviet Union's military and diplomatic codes. Now there is a distinct possibility that GCHQ may have unwittingly been providing information to the Soviets, a disaster that, if true, could nullify many of Britain's code-breaking efforts and jeopardize its intelligence links to the U.S.

This newest in a long string of British spy scandals came to light with the announcement that Geoffrey Arthur Prime, 44, a former employee of GCHQ, had been arrested and charged with violating Section 1 of Britain's Official Secrets Act. Officials would give no details of the accusations against Prime, but that section of the act deals with, among other things, the passing on of secret codes or documents to a potential enemy. A Russian-language specialist, Prime had worked at GCHQ from 1968 to 1977. He then left voluntarily and subsequently held jobs as a taxi driver and a wine salesman in the town of Cheltenham. At the time of his charging a fortnight ago, he was unemployed. His trial is scheduled to begin in November.

Britain would not be the only country affected by a breach of GCHQ security. The Cheltenham facility is part of a four-nation intelligence net that also includes the U.S., Canada and Australia. GCHQ shares its cryptographic expertise with Washington's top-secret National Security Agency (NSA), an organization that gathers intelligence based on electronic eavesdropping. In return, the NSA passes on some of its intelligence and provides technical assistance. Moreover, the U.S. maintains spy bases in Britain whose data are processed at GCHQ, and Cray I, the complicated computer that does most of Cheltenham's decoding, is American-made.

U.S. officials said last week that it was too soon to tell whether, or to what extent, Western intelligence had been compromised. It was clear, however, that Washington's patience was wearing thin. British spy scandals have been a Western burden since the days of Kim Philby and his fellow double agents, Donald Maclean and Guy Burgess, all Cambridge graduates and members of the old-boy network, who were unmasked as Soviet agents. U.S. spymasters say that they have tried ever since to persuade their British counterparts to tighten security, but with only limited success. "The British are very good at gathering and analyzing information," says one intelligence expert. But, he notes, "they do not keep their eye on their people."
