Pressure on David Cameron to explain why Andy Coulson was spared tough security and background checks increased as it emerged both his successor as director of communications and his former deputy are being vetted to a higher level than he ever was.
Labour called on the cabinet secretary, Sir Gus O'Donnell, to reveal who inside Downing Street decided not to seek the highest level of security clearance for the former News of the World editor and whether the decision was discussed with the prime minister. Ivan Lewis, the shadow culture secretary, said it was
"now a matter of urgency that this information is put into the public domain otherwise it will fuel the belief that there was knowledge about Andy Coulson's involvement in illegal activities before he was employed".Craig Oliver, a former BBC executive who replaced Coulson when he resigned from Number 10 in February, is undergoing "developed vetting" – a rigorous probe into his background and finances aimed at uncovering anything that could make him vulnerable to blackmail or other compromises. Coulson underwent less stringent checks.
A former senior counter-terrorism official said it was "unthinkable" and "very surprising, that someone would not be vetted to the higher 'DV' level when they are working in No 10, that close to the PM".
