Hillsborough investigation will be IPCC's biggest test, chairman admits She told The Guardian newspaper: "Clearly it is a test and a challenge. But it is also an opportunity for us to show what we can do if we are properly resourced to do a big job. The scale of it is very big but I think the way we are working with a team that includes investigators, lawyers and family liaison teams is critical and will be a model for the future, provided that we get the resources we need. The IPCC investigation will run alongside a criminal inquiry led by the former Chief Constable of Durham Jon Stoddart who will focus on who was to blame for deaths of the football supporters. Dame Ann has said she is currently in discussions with the Home Secretary over extra funding to cope with the demands placed on the IPCC by the investigation. Around 100 new investigators are already being recruited to the IPCC to bolster its staff as the Hillsborough investigation gets under way.
