The man in charge of Corporate Services Group (CSG) has claimed the company must move on after two of its former directors were jailed for fraud.

Roger Eden, 47, and Geoffrey Brailey, 51, were last month sentenced to three years and nine months’ imprisonment each, and were disqualified from acting as company directors for eight years.

CSG chief operating officer Mark Adams said: “The announcement of the jail sentence now closes an unfortunate period in the company’s history. The new management team can get on with rebuilding the group.”

A jury at Croydon Crown Court was unanimous in its decision that the two men were guilty of accounting irregularities designed to overstate profits in 1997 and 1998.

The court heard how Eden and Brailey fiddled the books in 1997 so that CSG’s results were overstated by £3m.

They instructed employees to make false and misleading entries into accounts, draw up bogus sales invoices and reinstate invoices that had been written off.

They also concealed debts to boost profits and in 1998 they intended to charge a substantial amount of the firm’s UK costs to a newly acquired American company.

The irregularities came to light in 1998, before the company’s results were due to be published.

Former company secretary, John Abrahamson, 57, was acquitted of the charges.

A statement in the firm’s results said the case would not impact CSG’s financial or trading position.
