The wife of Britain's new Secret Intelligence Service chief may have lost a few friends—virtual and otherwise—over the past few days. After publishing personal details and photos on Facebook of Sir John Sawers, who is set to become the new head of MI6 in November, spouse Shelley is being blamed for causing a major security breach and leaving their family and friends exposed. Sawers's role would include overseeing all of Britain’s spying operations abroad, but the information revealed may have compromised his position. To make matters worse, Sawer's wife put almost no privacy controls on her account, making the information available to more than 200 million users. Meanwhile, MI6 agents are advised to reveal their true role only to their closest family. Oops.
