What will happen to the UK if the Conservatives win a majority Government?

It will be Thatcherism on steroids just without the economic boom.

A Conservative majority government would mean a Conservative-run hard Brexit, which would run massively against the interests of working-class people in the country. A referendum vote built on the promise of £350 million a day extra for the National Health Service would likely lead to the exact opposite and leave open the possibility of trade deals including opening up parts of the NHS to American pharmaceutical companies.

Here is Trump refusing to rule it out:

Here is Nigel Farage (Mr Brexit), caught advocating an 'insurance-based' healthcare model:

Here is an article about 'Britania Unchained,' which is an ideological manifesto advocating further privatization of British service, slashing worker protections and further de-regulating businesses (including banks) and further tax cuts for the rich. Four of the five authors are current cabinet ministers and Boris wrote the foreword:

Here is leaked Whitehall document which shows that the government already have plans for a 'Singapore-style' free-market tax haven for Britain:

These are the ideological forces at work behind the Tory Brexit. These are not people who care about the working class of this country but are right-wing free-market ideologues who want to tilt the balance of power in this country even more onto the side of big business.

Now, if you want to make an argument for a Thatcherism on steroids version of Britain and the break-up of this country's already strained public sector, then I can argue that with you. However, this point is not being argued by the Conservatives and is in fact being semi-hidden because it would (rightly) be massively unpopular with the UK public. Neither Brexit voters nor remain voters want that to happen.

However, if the Conservatives win this election, then there will be little holding them back. They don't want to be free of the EU because of sovereignty but because they want to free of EU rules preventing them from doing what I described above. The migration issue always was a trojan horse for Ayn Randian economic libertarianism.
