Facebook refuses to disclose “chuck Chequers” Brexit advertiser to UK parliament

An unknown group, called ‘Mainstream Network’, ran a series of political ads on Facebook’s platform last year which targeted voters in key leave voting constituencies urging them to pressure on their member of parliament not to support the prime minister’s approach to seek a withdrawal deal from the EU. Last year research commissioned by a UK parliamentary committee as part of an enquiry into political advertising online spotlit the existence of Mainstream Network, estimating the unknown Facebook advertiser had spent ~£257,000 in just over 10 months. Last November Facebook policy VP Richard Allan faced questions from the DCMS committee about who is behind the ‘Mainstream Network’ Brexit ads running on Facebook.
