"You may not know what you were voting for ..... we cannot keep having referenda until you get the answer you want."
Who should decide? Certainly no individual, surely.
Therefore we ask "The People" two questions - do you want a second referendum, and if you do, would you vote in or out of the EU.
These can be asked at the same time - if more than 50% want a second referendum, then the answer to the second question counts, otherwise it doesn't.
