Is the Cambridge Analytica scandal cause enough to demand a second referendum?

Carole Chadwalladr’s piece in The Guardian outlines “what increasingly looks like a cover-up”. It sounds to me like laws have been broken, that the outcome of the referendum was manipulated, resulting in the vote to leave. On these grounds alone I would argue for a pause to Brexit proceedings until the truth can be clarified. It also raises the question, is this scandal cause enough to demand a second referendum?
