Stevenson needs Xtra help with banking definition

To the Treasury Select Committee where former HBOS chairman, Lord Stevenson, was trying desperately to demonstrate that he knows everything there is to know about banking.
Those efforts weren't helped, however, when Committee chairman, John McFall, read out the Oxford English Dictionary definition of a bank. Is that accurate, he asked?
"Could you read it out again?" stuttered Stevenson.
Excellent work, My Lord.
