A whistleblower claims he was fired by insurance giants Zurich after 'exposing a multi-million pound fraud', a tribunal has heard.
Software developer Artiom Borisov, 40, alleges he discovered a multi-million pound internal fraud case while working for the London branch of the Zurich Insurance Group.
But after alerting the company's fraud prevention and investigations unit of his belief their new IT project was a scam, he claims his allegations were not followed up on.
The software developer alleges his former employer intimidated him, cut him off from all IT systems and tried to cover up the fraud, eventually dismissing him in April 2019.
Representing himself, Mr Borisov is bringing a claim of unfair dismissal based on protected disclosure against the Swiss company at the Central London Employment Tribunal.
But Zurich says Mr Borisov was fired for ignoring management orders to not contact underwriters about the contested UW 360 IT project, which was due to replace the former system called Plum Z.
Two further alleged disciplinary violations include Mr Borisov trying to undermine the project and requesting access to a database he was not authorised to access.

Judge Emma Burns set out what Borisov, a Zurich employee for five and a half years, claimed: 'You say you have internally reported an IT project to be multi-million pound fraud.
'You say instead of an investigation it became a cover up scheme.
'Then you say you were intimidated, threatened not to contact anyone, accused of absurd offences and cut off from all Zurich IT systems.
'You were dismissed for gross misconduct.'
Mr Borisov had already been working on another IT project Plum Z, which the tribunal heard was going to be decommissioned and replaced by UW 360.
He contacted underwriters to establish and spoke with Zurich's internal ethics team to allege there were potential criminal ramifications with the UW 360 project, but was warned he was being placed at risk of redundancy in February 2019.
