Vote Leave has rejected claims that it illegally co-ordinated with the BeLeave campaign

Vote Leave, the organisation that campaigned for Britain to exit the European Union, has drawn new allegations from a whistleblower.

Mark Gettleson, who worked on communications and web design for Vote Leave, has made a submission through lawyers to the Electoral Commission, alleging that it sought to sidestep spending limits during the referendum campaign.

His lawyer said his submission demonstrated that the youth campaign group BeLeave was part of Vote Leave, and that the money spent by BeLeave should have been part of Vote Leave’s £7 million campaign spending limit.

Mr Gettleson’s evidence includes invoices for BeLeave charged to Vote Leave, which has said that the two were separate organisations. Vote Leave has rejected claims that the groups were involved in illegal co-ordination.
