A second referendum would undermine British democracy. It would send a message to the British people that a majority vote is not enough weight to provide legitimacy and certainty to decisions.
It might give a more accurate understanding of what people want regarding Brexit, but it would undermine all future political elections, further foster divisions and strip any future government of political legitimacy.
It would set a precedent that once the original conditions for a vote changed, the people should have a chance to vote again on the same issue. If this is applied to the future political landscape, it would mean more regular public votes and breakdown of democracy.
Besides, although people may not like the idea of Brexit, they don’t want a second vote. Polling has found that the public desire for a second vote is low.
Last year, just 31% of people thought the UK should hold a second referendum. This year it has risen, but not by much. In July 2018, just 42% of the public were in favour of holding a second referendum.
Even though many voters regret the outcome of the 2016 referendum, most still believe it should go ahead in some form. Even remain voters expressed desires for Brexit to go ahead out of respect for the democratic result of the first referendum.
