The same polls that told us Remain would win, that Trump would lose and that, during May’s snap election, the Tories would win by a landslide? Ok then have fun with that.
Actually, the polls toold us it would be a close result but favoured a Remain win (although 4 of the last 10 polls had Leave wins), they showed that Hillary would win more of the vote than Trump (she did, it's the electoral college which saved his backside) and the polls narrowed increasingly during that campaign (indeed Survation the day before the election called it basically spot on).
