Ads by secretive organisation Mainstream Network may have breached personal privacy rules
A secretive group that has spent hundreds of thousands of pounds encouraging voters to back a hard Brexit is being investigated by Britain’s data watchdog, it has emerged.
MPs had already raised concerns about the activities of the anonymous Mainstream Network group, whose ads and website encourage readers to “chuck Chequers”, referring to Theresa May’s proposed Brexit deal. It is has been estimated that it could have spent up to £250,000 on the ads.
