Brexit crisis: the agencies behind the Remain advertising campaign have shared their unsuccessful designs and described a "frustrating" process that was "doomed" to fail (+ slideshow). 
Both Saatchi & Saatchi and M&C Saatchi created posters for Remain's Stronger In campaign ahead of the referendum, in which the UK voted to leave the European Union.

"We never normally release work that we produced on behalf of a client but that hasn't run," worldwide chief executive of M&C Saatchi Moray MacLennan told marketing industry magazine Campaign.
"But this time is different. We are still emotionally engaged, the issue is ? and will remain ? of vital importance and it might help to air some of these ideas."
The posters criticise Leave campaigners like Nigel Farage, then head of the UK Independence Party, which came under repeated scrutiny for racist comments.
Saatchi & Saatchi's design features Farage with a black microphone placed beneath his nose to look like a Hitler-style moustache. Red text reads "Remain, sane."
