Wylie's comments spark war of words between Congress, BJP

Cambridge Analytica whistleblower Christopher Wylie's remarks that Congress was one of the parties that had used the services of the tainted company, triggered a war of words between the Congress and the BJP.

Senior BJP leader and Union Law Minister Ravishankar Prasad said Wylie's testimony in United Kingdom's Parliament has confirmed that Cambridge Analytica worked with the Congress.

"This has exposed Rahul Gandhi, who was denying all along. Congress and Rahul Gandhi must now apologise," Prasad told reporters.

Countering the BJP charge, Congress chief spokesperson Randeep Surjewala said, "It is all false. Why is India's perpetually lying Law Minister throwing allegations in the media; he is in power, why doesn't he show all proof and then register an FIR. We challenge you. They fear they will be exposed if they probe."

Congress and BJP were accusing each other of using the services of the disgraced data mining firm for the elections.

During his deposition before the UK Parliament, Wylie said, "I believe their (Cambridge Analytica) client was Congress. I don't remember a national project but I know regionally. India is so big that one state can be as big as Britain.
