Any referendum or election result can be rethought and changed after time.
The referendum in which we voted to join what is now the EU was reversed in 2016.
Any General Election can lead to a change of government.
However, any suggestion that the referendum of 2016 could EVER be reversed is pounced on as a denial of the democratic will of the people!

It is.
I wonder how long Brexit is supposed to continue - until all those who voted for it are dead and gone?
However, a referendum isn't quite like an election, I suppose. But what is the statute of limitation on Brexit?
It was costly to leave and would be costly to re-join and would, I'm sure, take years to completion. But in theory it could be done?
... and some are accusing Starmer of wanting to do just that. Personally, I don't think they are paying attention. Starmer may be or not be lots of things, but he's not a fool. He knows jolly well that any tampering with the Brexit vote would see him in deep trouble. He's not going to try to take us back in, he just wants a more civilised and equitable relationship with the EU and Europe. But for some, even that is far too much to tolerate.
It's sovereignty and all that - but when you see how much of our services and industry is foreign owned, you do have to question quite what sovereignty means. Other than our freedom to choose who invests in and profits from our services and industries. But I think we were able to do that anyway, and did.
IMO sovereignty means having a seat at the table and a voice in the debate. And now we are at the mercy of countries and unions that are bigger than us.
