Crispin Odey, the multimillionaire financier fighting various lawsuits relating to allegations of sexual misconduct, is to launch a case against the financial services regulator over his exile from the City.

The Financial Conduct Authority (FCA) fined Odey £1.8m and banned him from the financial services industry last year.

It found that he had displayed a “lack of integrity” by attempting to frustrate an investigation by his own hedge fund into allegations of sexual harassment, which he denies.

Odey had already launched a £79m libel claim against the Financial Times, which first published claims about his behaviour towards junior female staff. The fund, Odey Asset Management, shut down in the wake of the allegations.

He is also facing civil personal injury claims by five women, including one who accused him of rape, which he also denies.

Those cases are scheduled to be heard together in joint proceedings in June.

Odey will begin a separate legal case on Tuesday against the FCA over the disciplinary action it took in response to his alleged obstruction of an internal investigation into his behaviour that was launched in September 2020.

According to the regulator’s opening submission, Odey wielded his power as the fund’s majority shareholder to bypass governance structures and protect his own position in breach of City rules.

The FCA claims he is not a fit and proper person to run a financial services company, having shown a “reckless disregard” for compliance that caused the company to breach its regulatory obligations.

Odey’s case against the FCA has previously led to the disclosure that an internal report into his conduct uncovered at least 46 historical allegations of inappropriate conduct towards female employees.

In his opening submission, Odey will say that FCA officials had a “hostile animus” towards him, referring to emails between staff at the regulator, one of which referred to him as presiding over a “culture where it’s okay to be a perv”.

He claims the regulator pre-judged the outcome of its investigation, which began in November 2021 and concluded in December 2022.

The process was unfair, he will say, insisting the actions he took were necessary for the fund’s survival rather than geared towards self-preservation.

Odey claims he was entitled to dismiss members of the company’s executive committee who were leading the investigation against him, believing they were not able to conduct the process fairly. He will say he dismissed them in order to save the company from collapse.
