Following the riots in England in August 2011, Miliband called for a public inquiry into the events, and insisted society had "to avoid simplistic answers". The call for an inquiry was rejected by David Cameron, prompting Miliband to say he would set up his own. In a BBC Radio 4 interview shortly after the riots, Miliband spoke of an irresponsibility that applied not only to the people involved in the riots, but "wherever we find it in our society. We've seen in the past few years...MPs' expenses, what happened in the banks". Miliband also said Labour did not do enough to tackle moral problems during its 13 years in office. In December 2011 Miliband appointed Tim Livesey, a former adviser to the Archbishop of Canterbury, to be his full-time chief of staff.
