Boris Johnson says Brexit whistleblower’s claims are ‘ludicrous’

Boris Johnson has dismissed as ‘ludicrous’ claims the Brexit campaign broke election spending rules. His comments come after a Whistleblower for the ‘Vote Leave’ campaign group told this programme that their side cheated on how much they spent on digital campaigning and targetted ads on platforms like Facebook.

Labour’s Deputy Leader said a police investigation may be needed.
