Would a second Brexit referendum change anything?

According to a new survey by YouGov, a plurality of the British public think that a second Brexit referendum would lead to an overturning of the 2016 result and see the UK remaining a part of the European Union. Unsurprisingly, this sentiment is most common among those who voted to remain in the first place, but even leave voters are somewhat split, with 26 percent saying they think remainers would win.
