The Crown Prosecution Service is to press ahead with a retrial of a prison officer whose conviction on a charge of leaking stories to newspapers was overturned by the Court of Appeal last week.

The Lord Chief Justice, Lord Thomas of Cwmgiedd, sitting in a special hearing of the Court of Appeal yesterday, gave the CPS permission to go ahead with a retrial.

But the CPS said it had concluded that it was not in the public interest to seek a retrial of the prison officer's co-defendants, one who was a friend, and the other a former News of the World journalist.
