Two former bankers have lost their appeals over convictions arising from a €7.2bn conspiracy to defraud the public about Anglo Irish Bank.

Irish Life & Permanent's former CEO Denis Casey and former Anglo executive John Bowe were jailed last July following a lengthy and complex trial.

When handing down sentences almost one year ago, Judge Martin Nolan described what the former banking executives did as a "deceitful and corrupt crime" that could have affected thousands of people.

They were found guilty of taking part in a conspiracy designed to fool the public about the health of Anglo Irish Bank in the six months leading up to the end of 2008.

Casey was sentenced to two years and nine months in prison, and Bowe was jailed for two.

They appealed their convictions on a number of grounds - including the admissibility of expert evidence and the judge's directions to the jury.

In dismissing their appeals today, Mr Justice Sean Ryan said the court found Judge Nolan exercised his function carefully and correctly and was therefore satisfied the convictions were safe and satisfactory.
