Richard Carr, the former chief executive of car parts manufacturer TransTec, has been struck off the ICAEW register due to the company’s accounting issues.

Former finance director Richard Parkin was also severely reprimanded by the Joint Disciplinary Scheme.

Debit notes of £11m issued to TransTec by its client Ford ­ compensation to the car firm for poor work by TransTec ­ were not properly disclosed in the accounts and were withheld from the board, auditors and shareholders.

Carr and Parkin admitted to the mistakes before the tribunal, which meant that no costs were awarded against them.

The tribunal said Carr’s misconduct ‘was of a serious and sustained nature’, while Parkin’s failings were ‘a serious dereliction of duty’. There was a ‘culture of secrecy’ at TransTec in its accounting, with Parkin criticised for failing to ‘act with proper objectivity and propriety in that he continued the culture of secrecy and lack of candour by Carr and Jeffrey,’ the tribunal said. William Jeffrey was group FD before Parkin and is a lapsed ICAEW member.

TransTec was first investigated in June 2000.
