Christopher Wylie, a former Cambridge Analytica employee, recently testified before a British parliamentary committee that is investigating fake news where he asserted that the Congress was a client of the disgraced firm.

Labour MP Paul Farrelly, a member of the parliamentary committee, while asking questions, had asked the whistleblower about the firm's role in India, he asked, “When you look at Facebook's biggest market, India is the top in terms of numbers of users. Obviously, that's a country which is rife with political discord and opportunities for destabilisation.”

To which Wylie responded, :They (Cambridge Analytica) worked extensively in India. They have an office in India.”

He added, “I believe their client was Congress. But I know that they have done all kind of projects. I don't remember any national project, but regionally, India is so big that one state can be the size of Britain. They do have offices there, staff there. I believe I have some documentation on India which I can provide if you're interested.”

Wylie also revealed that his predecessor Dan Muresan had been working in India before he died in Kenya under mysterious circumstances. He said that he had heard rumours that Muresan, a Romanian national, may have been poisoned in a hotel room while in the African country.

Paul-Olivier Dehaye, a data protection specialist who had a role in the investigations, however, added that, “According to reports from India, apparently he was really paid for by an Indian billionaire who actually wanted the Congress to lose. So he was pretending to work for one party but really paid underhand by others.”

Soon after the testimony details emerged, the BJP said Congress president Rahul Gandhi had been exposed and should apologise.

However the Congress dismissed the attempt to link it to the political consulting firm.
