<p><br /> Details of the "personal issues" that forced shadow chancellor Alan Johnson to quit are starting to emerge amid allegations that the politician's bodyguard had an affair with his wife.<br /> </p><p><br /> Mr Johnson's close protection officer when he was home secretary, Paul Rice, is facing an internal Scotland Yard inquiry over his alleged behaviour.<br /> </p><p><br /> A decision is expected to be taken shortly on whether the constable will be suspended or relieved of duty while the probe takes place.<br /> </p><p><br /> Mr Johnson quit as shadow chancellor on Thursday over what he described as "personal issues in my private life".<br /> </p><p><br /> The officer is now protecting Home Secretary Theresa May.<br /> </p><p><br /> Asked to comment on the report, a Scotland Yard spokesman said "certain matters regarding an MPS (Metropolitan Police Service) PC were referred to the directorate of professional standards. We are not in a position to discuss further at this time."<br /> </p><p><br /> Mr Johnson's spokesman refused to comment on the claims, while the Home Office said it did not comment on personal security measures.<br /> </p><p><br /> In his statement, Mr Johnson said only that it was "to do with my family. I have found it difficult to cope with these personal issues in my private life whilst carrying out an important front bench role," he added.<br /> </p><p><br /> Mr Johnson has been married to his second wife Laura for almost 20 years and the couple have a ten-year-old son.<br /> </p><p><br /> His resignation left Ed Miliband facing his biggest test since being elected Labour leader, forcing him to reshuffle his shadow cabinet less than four months into the job.<br /> </p><p><br /> He installed Ed Balls as shadow chancellor after overlooking him last October.<br /> </p><p><br /> Amid suggestions that Mr Balls may drag Labour to the left, Mr Miliband stressed that there would be no change in economic policy.<br /> </p><p><br /> Mr Balls, a fierce ally of former prime minister Gordon Brown, has questioned Labour's deficit reduction plans in the past, suggesting they should be less aggressive.<br /> </p>
