In 1966, the Liberals began to make an issue of the Munsinger affair—two officials of the Diefenbaker government had slept with a woman suspected of being a Soviet spy. In what Diefenbaker saw as a partisan attack, Pearson established a one-man Royal Commission, which, according to Diefenbaker biographer Smith, indulged in "three months of reckless political inquisition". By the time the commission issued its report, Diefenbaker and other former ministers had long since withdrawn their counsel from the proceedings. The report faulted Diefenbaker for not dismissing the ministers in question, but found no actual security breach.
