Stafford Hospital: 'We're still not getting answers'
A public inquiry into the scandal-hit Stafford Hospital has begun, years after campaigners first demanded an open hearing.
A 2009 report condemned conditions at the hospital, said to have caused hundreds of avoidable deaths.
Michael O'Callaghan's father died at the hospital in December 2006. He says he wants to ensure that cases like his father's death never happen again.
