The Co-operative Group has announced annual losses of £2.5 billion after suffering the worst crisis in its history following the near-collapse of its banking arm.
Interim chief executive Richard Pennycook said: "2013 was a disastrous year for the Co-operative Group, the worst in our 150-year history.
"Today's results demonstrate that but they also highlight fundamental failings in management and governance at the group over many years.
"These results should serve as a wake-up call to anyone who doubts just how serious the challenges we face are."
