I will probably not do a very good of explaining this, but...there has been a lot of talk around the UK-US trade deal and what that's going to mean for drug prices if access to the NHS is a part of it. The NHS has a monopoly (or close enough) on drug purchasing in the UK, so drug prices here are much cheaper.
The worst thing is that they've already talked about it.
This article explains the leaked US-UK trade deal document better than I could. Both Trump and Boris have denied the NHS would be on the table during negotiations, but it's already been discussed, and Trump has done far too much whining about the prices paid for US drugs, so their denials aren't really all that credible. As is typical of politicians, they've done a complete turnaround - Trump first said that everything would be on the table if there was a US-UK trade deal, and more recently he said he wanted nothing to do with the NHS...to bolster Boris' position, no doubt. Within a few months he's going to be saying the NHS needs to be part of the deal again, and now that Boris has no limits on what he can do, he is probably going to agree under the justification that it's the only way to get a trade deal with the US, or that the benefits gained will make up for that one small concession.
If the NHS gets privatised, the cost of drugs - and the prices - are going to skyrocket. A lot of people in the US can't afford medical treatment, and a trade deal that included the NHS would likely see the same circumstances in the UK. The NHS is by no means a perfect system, but in this country you're entitled to free healthcare regardless of how much money you have. That seems to offend the Conservative Party, who have consistently strangled the NHS with budget cuts since they came into power. A trade deal with the US that included the NHS would likely be justified as a way to inject more money into the system, but it'd be the taxpayer who footed the bill once the drug prices started rising.
tl;dr Selling the NHS to Trump is more about allowing US drug firms more access to it and the inevitable rising costs that would ensue.
...maybe I'm exaggerating or jumping to conclusions, or have no idea what I'm talking about. But as far as I'm concerned they shouldn't be discussing privatising the national health service at all.
I think it's almost guaranteed at this point that indyref2 - a second Scottish independence referendum - is going to happen, and this time the Scottish people will vote to Leave. Scotland voted primarily to Remain in the 2016 EU referendum, and Nicola Sturgeon has been raving on about how England voting to Leave and Scotland voting to Remain gives them mandate for a second independence referendum.
The SNP won significantly more seats in this election, and she's already said that she is going to formally request it on that basis, and whilst Boris will refuse, she will probably take it to the courts. Whether or not the UK Supreme Court would find in her favour remains to be seen. But there is a Scottish Parliament election in 2021, and if the SNP win a majority in that, indyref2 will happen if it doesn't before then.
...of course, this is assuming that Brexit is an unmitigated disaster and the Scottish people vote for the SNP in the 2021 Scottish Parliament election. But I have absolutely no faith in Boris making anything other than a mess of it.
I'm not a politics student, there is a lot of misinformation and rhetoric floating around on the internet and circulating in amongst parties - I mean, misinformation is basically the main reason Brexit is a thing in the first place - and I expect there are other people here with a better grasp of the realities of the situation than I have. But at the very least, the existence of a US-UK trade deal document with drug patents and prices being discussed doesn't really bode well, and it's not hard to imagine the SNP duplicating the circumstances the first independence referendum were held under in the near future, and the result going a very different way this time.
