Andrew Meeson has resigned from his post as president of the Association of Taxation Technicians (ATT), as an HMRC investigation focuses on his company, Tudor Capital Management (TCM).
The Revenue is looking into a pension scheme administered by TCM and believes the firm has been involved in fraudulent activity. The case is likely to come to court during the second half of 2012. Mr Meeson and his colleagues reject the taxman's allegations and say they will fight hard to clear their names.
The investigation began last year, before Mr Meeson became ATT president. Asked why he did not postpone his presidency while the matter was hanging over him, an ATT spokesperson said that, at the time of Mr Meeson's appointment in May this year, it was not thought probable that the case would go to trial.
ATT deputy president Stuart McKinnon will stand in for Mr Meeson, who will step down from the organisation's council. Its December meeting will be asked to appoint Mr McKinnon as president with immediate effect.
