SIR – Christopher Hindle (Letters, November 26) rightly identifies Kweku Adoboli, the unsuccessful UBS trader, as a sacrificial lamb following his seven-year prison sentence, but it’s even worse when you consider his actual ‘crime’.

Imagine that you were a print-worker and, by deliberately ignoring management instructions, you printed a million calendars with 31 days in February, causing your employer significant wastage and losses.

The worst case scenario would be a disciplinary procedure, with the ultimate sanction being the loss of your job. Fair enough.

What Kweku Adoboli did was no different. All he did was to do his job badly, in contravention on company instructions, yet he was dragged before the criminal courts for an alleged ‘fraud’ (with no personal gain, remember), and he got seven years in jail.

Somehow the corrupt financial services sector manages to exploit the criminal justice system to handle what should only be its own internal management issues.

There was no fraud, therefore there was no crime, but there's still a broken bloke in jail.
