The Sheridans' family solicitor Aamer Anwar has said that today's revelation contained in Clive Goodman's letter released by the Culture, Media and Sport Committee reveals "a serious contradiction of the evidence given by Andrew Coulson during the Perjury Trial of Tommy Sheridan."

He adds that "if it is shown that people lied in the Glasgow High Court they should go to prison."

Anwar also told The Firm exclusively that more information will be dislcosed on this subject next week.

"Today the Culture,Media & Sport Select Committee disclosed that it was alleged that Andy Coulson was aware of phone hacking. If true this is a serious contradiction of the evidence given by Andrew Coulson during the Perjury Trial of Tommy Sheridan," he said.

"Strathclyde Police's majory inquiry into perjury and phonehacking should now consider interviewing Clive Goodman as well as Andy Coulson.

"We were told repeatedly during Mr Sheridan’s trial by the police and the Crown, that perjury strikes at the heart of the administration of justice and nobody was above the law. We now expect to see a similar robust response to News of the World and for arrests to take place in Scotland, and if it is shown that people lied in the Glasgow High Court they should go to prison.”

Strathclyde Police have yet to comment on how the latest revelations will impact upon their ongoing investigations.
