Former Head of MI6 Sir John Sawers, "Russia was very keen that the Leave campaign should succeed and that Britain should leave the European Union" "Because that would marginalise Britain as a global player and weaken Europe in general" "That's the strategic opportunity the Russians spotted, and the leaders of the Leave campaign fell into it" My view: Former MI6 chief Sir John Sawers says Russia saw Brexit as a way to weaken Britain and divide Europe, and that the Leave campaign’s leaders walked straight into the opportunity. So let’s remember who sold it: VOTE LEAVE • Boris Johnson — political figurehead • Michael Gove and Gisela Stuart — campaign committee co-convenors • Matthew Elliott — chief executive • Dominic Cummings — campaign director • Daniel Hannan — leading Brexit advocate • Priti Patel, Iain Duncan Smith, Chris Grayling, John Whittingdale and Theresa Villiers — senior Conservative campaigners • David Davis, Liam Fox, Dominic Raab, Steve Baker and Douglas Carswell — prominent Leave campaigners LEAVE. EU • Nigel Farage — leading political figure • Arron Banks — co-chairman and major funder • Andy Wigmore — communications director GRASSROOTS OUT / LABOUR LEAVE • Peter Bone and Tom Pursglove — Grassroots Out co-founders • Kate Hoey — Grassroots Out co-founder and Labour Leave campaigner • Graham Stringer, Kelvin Hopkins and Roger Godsiff — Labour Leave campaigners • Sammy Wilson — prominent DUP Leave campaigner They promised Brexit would make Britain stronger. Sawers says Russia saw the opposite opportunity: a Britain marginalised and a Europe weakened.
