article: Coulson was convicted on Tuesday of conspiracy to hack phones. Goodman had already pleaded guilty in 2006. But jurors could not decide on charges against the pair of conspiracy to commit misconduct in public office. The judge criticised David Cameron for commenting on the case while the jury was still deliberating. Meanwhile, the BBC has learned that one of the phone hacking victims was Carole Middleton, the Duchess of Cambridge's mother. On Tuesday the prime minister apologised for employing Coulson as his communications chief but that he had done so "on the basis of undertakings I was given by him about phone hacking and those turned out not to be the case." Coulson's lawyer criticised Mr Cameron's "ill-advised and premature intervention" in the case - a move described as "unwise" by former lord chancellor Ken Clarke. The judge commented: "I consider that what has happened is unsatisfactory so far as justice and the rule of law are concerned." Discharging the jury at the Old Bailey, Mr Justice Saunders said a decision on any retrial would be made on Monday. Five people have pleaded guilty in the case, while former News International chief executive Rebekah Brooks and her husband Charlie were among the remaining defendants cleared on Tuesday. Mr Cameron faced criticism from Labour leader Ed Miliband at Prime Minister's Questions for his decision to take Coulson with him into Downing Street. Labour wants an investigation into why Coulson did not receive the highest level of security vetting when he joined the No. 10 operation. But Mr Cameron insisted it had been the civil service's role to vet the appointment and that he had been exonerated by a public inquiry following the hacking scandal. "Every single one of these issues was dealt with exhaustively by the Leveson Inquiry," the prime minster told MPs. "He looked into all of these questions about the warnings I was given and the response I gave and he made no criticism of my conduct." The BBC's Robert Peston said that, if there was to be an investigation, it would be head of the civil service, Sir Jeremy Heywood, facing embarrassment over the failure to vet Coulson. However, Mr Miliband listed a string of allegations about the PM's role, insisting: "When it came to Andy Coulson, you just didn't want to know the evidence. "This is about your character, your judgement and the warnings you ignored." Mr Cameron appointed Coulson as his official spokesman after becoming prime minister in 2010, only for the former News of the World editor to resign in 2011 amid growing allegations about phone hacking at the paper. The prime minister had become "the first ever occupant of his office who brought a criminal into the heart of Downing Street", Mr Miliband added.
