Over 3 million people have signed a petition for another Eu vote on the grounds that if the remain or leave vote is less than 60% based a turnout less than 75% there should be another referendum. https://petition.parliament.uk/petitions/131215
I know a fair few people who voted out and feel they were misled. I also know a few people who voted out who didn't really do any research, they just though everyone else would vote in. In my opinion if there were a second vote it would be a very different result.
