Names of blue-chip hacking companies could be released after Soca chief resigns Sir Ian has had four decades of distinguished public service in roles ranging from second permanent secretary and chief executive of Defence Estates, to his current position as the chairman of Soca. An interim appointment will be made in due course. A Soca spokeswoman: "The Home Secretary has today accepted the resignation of Sir Ian Andrews as chair of the Soca board. Sir Ian offered his resignation after realising he had neglected to register his directorship of Abis Partnership Ltd. The Soca code demands that all directors' interests are declared. Sir Ian wrote to the Home Affairs Select Committee after it emerged last week that his wife worked for investigations firm G3. He told the group of MPs that it was a "matter of public record that my wife, Moira Andrews, after leaving the Foreign and Commonwealth Office in 2011 and amongst other independent interests, became General Counsel of G3, a role she has filled since 2012 as a part-time consultant." Pressure has been mounting on Sir Ian and Soca to release the names of hundreds of companies and individuals linked to its Operation Millipede, which led to the conviction of four private detectives for fraud last year. The list features eight firms that featured in evidence in the prosecutions, as well as 94 other organisations which were relevant to the inquiry but not used in evidence. A total of 22 law firms feature on the 102-strong list, alongside several insurance companies, financial services groups and two celebrities, among others.
