Background: Cheating may have swayed Brexit poll - Christopher Wyliepublished at 12:29 British Summer Time 29 March 2018
The UK may not have voted for Brexit if it had not been for "cheating" by the Leave campaign, a former employee of Cambridge Analytica has claimed.
Christopher Wylie said Vote Leave and other pro-Brexit groups had a "common plan" to get round spending controls.
He told MPs they all used Aggregate IQ, a "franchise" of the data analytics firm, to target swing voters, using information drawn from CA's databases.
Cambridge Analytica said it had played "no role" in the Brexit referendum.
The firm accused Mr Wylie, who it said had no "direct knowledge" of its work after he left the firm in July 2014, of peddling "false information, speculation, and completely unfounded conspiracy theories".
