Scottish police have arrested and charged Andy Coulson, the former communications chief of British Prime Minister David Cameron and former editor of News Corp.’s News of the World tabloid, of committing perjury before the High Court in Glasgow, the Wall Street Journal reports. Coulson was taken to Scotland for questioning about his testimony at the perjury trial of former Scottish politician Tommy Sheridan in 2010. On the witness stand in that case, Coulson denied there was a culture of phone hacking at News of the World during his tenure. The paper alleged Sheridan had visited a swingers’ club. Sheridan was convicted of perjury and recently got out of prison.
