The demands of this petition will not be met. There will be no immediate replay of the Brexit referendum.<p>However, suppose the UK and the EU agree on terms for leaving – could there be another referendum to approve those specific terms? Obviously many of those who supported Remain will demand that; but, it's concievable even some Leave supporters might, if they don't like those terms. For example, what if the agreed terms include keeping freedom of movement between the EU and the UK, so the UK still has to accept unlimited immigration from the EU? In that case, it's plausible that anti-immigration Leave supporters might join the calls for a second referendum. There's no legal requirement for such a second referendum, but it might be politically appealling if the future post-Cameron UK Government starts to have doubts about the whole thing, or if public opinion on Brexit begins to sour. Now, the UK has voted "Yes" to a Brexit in principle, and obviously if such a second referendum got a "Yes" the UK would be out for sure. But what if the vote was "No" to the specific terms for leaving? If you want to leave but can't reach agreement on terms to do so, do you stay in by default?
