A senior female City executive told by her boss 'women should stay at home and cook' has won a £75,000 payout.
Lana Sinelnikova had accused chief executive Alex Pusco of sex discrimination and blew the whistle on alleged improper financial practices at the foreign exchange trading company he founded.
The 37-year-old - who earned more than £100,000 - claimed he also showed staff at ActivTrades a 'degrading' picture of a woman wearing skimpy clothing posing with a car while declaring that 'sex sells'.
A tribunal heard Ms Sinelnikova had been suspended from her role as Head of Compliance for gross misconduct for taking a work trip to Dubai with a senior colleague she was in a relationship with, while she was off sick.
But the panel concluded that the firm - which believed she obstructed deals by flagging potential legal concerns - had been trying to force her out and used the trip as 'leverage' to fire her.
ActivTrades was found guilty of unfair dismissal and victimisation.

When she complained about her treatment, the company - which made £11 million profit in 2018 - embarked on a campaign of 'concerted and malicious action' against her, the tribunal heard.
This included giving false information about her to the Financial Conduct Authority (FCA), wrongly claiming she had committed a criminal offence and threatening to take her to the High Court.
It accused her of improperly using her work computer to run an ebay motors uk trading account.
The company also refused to give back her personal data, including details about her divorce.
The tribunal found the firm guilty of victimising Miss Sinelnikova after she accused them of sex discrimination and blew the whistle on what she believed were potentially criminal practices at the firm.
The hearing, in East London, was told Ms Sinelnikova had joined the London-based trading firm in 2011.
At the time of her complaint, she said she was the only senior female manager working there.
The tribunal heard her role was to make sure the company's financial dealings were legal and to raise Suspicious Activity Reports (SARs) if she had concerns.
However, the tribunal heard that by 2017 there was growing frustration with her among senior management that she was obstructing deals by flagging up potential regulatory breaches.
In November of that year - despite being absent from work due to illness - Ms Sinelnikova travelled to Dubai with the firm's Compliance Director, Jon Friend, with whom she was in a relationship, to help carry out a risk assessment of the company's office there.
The company then used the trip as an excuse to get rid of her, the tribunal concluded, by claiming it was unauthorised.

'(AtivTrades) was looking to force (her) from the business at this time...as a result (it) was looking for a reason why (she) should leave the business,' the tribunal judgement found.
'It jumped to the conclusion that she had committed gross misconduct.'
In December 2017, Ms Sinelnikova issued a grievance against the company - later sent to the FCA - accusing them of sex discrimination and potential criminal offences relating to their compliance with financial conduct laws.
In her complaint, she recalled an incident at the firm's Bulgarian office when 'Mr Pusco stated that 'women should stay at home and cook', in the context of complaining about the length of maternity leave in Bulgaria.'
She also alleged that in 2017, 'Mr Pusco displayed an image of an advertisement by Aston Martin for pre-owned cars.
The advert contains a woman wearing limited clothing in a particular pose.
'On showing this advert to (Ms Sinelnikova) and others at the London Office, Mr Pusco stated that the (firm's) marketing needed to be 'sexy' and that sex sells.
