Some have speculated that by resigning as Prime Minister, effective not-quite-immediately, David Cameron may have in effect annulled the UK's referendum result of a 51% majority voting for the UK to leave the European Union (EU) after more than 40 years of membership?
It's a political lifetime between now and the Conservative party conference the 2nd – 5th of October when a new leader (and thus UK Prime Minister) will be determined officially.
Denmark in 1992 voted by 51% to not join the EU, were granted carve-outs/exemption by the EU, and then put it up to a second vote in 1993 that passed with 56.7% and a huge, 86% voter turnout.
Things were very different then, and that was a vote to join not a vote on whether or not to leave. Then it was not nearly as much a time of globalization and certainly not a time of migrant crises or the depressing, disruptive wake of the Great Recession which sees banks get bailouts, billionaires continuing to get tax breaks, the middle class getting squeezed worse than ever, and the working class largely ignored.
Regardless, the EU's leaders are more scared now than they care to let on about possible exit movements in other nations, including France and the Netherlands, so they might be willing to grant the UK carve-outs as an inducement to stay.
Or not. They're very angry. Anyway, Cameron said the EU Referendum was a once-in-a-generation vote. On the other hand, it's not going to be his Government leading the negotiations. But, that's yet a further complication: it's not clear who will be at the helm in the UK during negotiations. It may be too many of the true-believer, deeply Euroskeptic lot who aren't interested carve-outs, just the best sort of EEA (European Economic Area, which includes non-EU nations such as Norway) or EEA-style bi-lateral arrangement they can get.
For now and for the short term, the UK is still the world's 5th or 6th largest economy, 4th or 5th largest military power (it depends on how one measures these things), gateway to Europe, and home to the profoundly important financial services and banking city that is London. If those things start quite quickly to look to be in real jeopardy because of Brexit, something (probably quite messy) might get worked out, even if it doesn't involve a 2nd referendum.
