I was a remainer but unfortunately I don't think rejoining would win a vote any time soon.

We had a good deal when we were in the EU and won't get the same terms - and joining under the standard terms (Eurozone membership, common agricultural policy etc) would not be attractive. It'll be harder fight to electorally to rejoin than it was to stay in, at least at the moment.

I think it's more likely we will fudge rejoin by rejoining the single market, taking the rules without a say but it's hardly any party's priority. The tories have imploded and Labour dare not mention the EU as all they care about is winning the election this year. The EU just isn't talked about as an electoral issue anymore.

Also I should say from within the UK, leaving the EU hasn't felt particularly negative. Our economic problems started before we left the EU with the financial crisis in 2011, so we were used to "austerity"and anemic growth. Also while the country hasn't grown it also hasn't contracted, it's stagnated. That's not good but it's not as impactful on ordinary people. And Covid had also been a distraction - a lot of economic harm has been blamed on Covid even though the EU and USA in particular have more than bounced back while the UK has only really gone back to baseline.

So for most UK citizens we haven't seen the doom and gloom that was warned about specifically from leaving the EU, hence the lack of a push to rejoin.

I think it may be some years yet before rejoining the EU is on the cards. And in fairness there is a lot that could be done to improve growth even without rejoining the EU - so I suspect it'll be ignored as an issue for at least the next parliament (5 years).
