Hi there,
I'm a company director (no shares), and discovered late last year that the MD and majority shareholder were committing fraud (fraudulent invoices from ghost employees, tax evasion) for financial gain. Over teh Christmas break I grabbed all the books and now have concrete evidence.
I have notified the police who advised me to call the HMRC hotline - this was done back on 29/12/14 and I'm still waiting to hear back from them.
Returning to work on Jan 5th, I confronted the MD and shareholder, and they put me on garden leave. A letter from their solicitor the following day
