Hello and Welcome to justanswer..
My name is MIKE - Im happy to help / advise you with this.
First, Im sorry to hear of the issue you have - its very disappointing to say the least when you purchase a vehicle and have such issues.
Ok well, the first thing to say is - the fact that "it will pass the MOT" - is irrelevant... why they said that I really dont know- they know its irrelevant. The clutch is not covered by anything to do with an MOT.
What is covered -by the trading standards act - is that the vehicle must be of merchantable quality and fit for purpose.
I cant go into giving you any legal advice , Im not allowed but I can tell you that much - and that if you need to , you can ask your local TSO ( trading standards office ) for help and back up with them on that ..
The trouble with clutches is - they are a "wear and tear" item - so any garage, can claim that its not covered by any warranty - though all warranties are different so I suggest first to check the "whats covered" section... and go from there then on that.
If its not covered - and if the clutch is really on its last legs- and not going to last you much longer at all - then you can go down the lines of "merchantable quality" etc as above.
You would need to check things as above though - get your facts etc all correct first before approaching the garage again.... that will give you a better chance of "no hassle success"... ie, its no good to just go and "demand"... much better to do it that way to have a chance of a free clutch out of them for the reasons mentioned above.
Let me know if you need anything more on this though.... Im always happy to help more / advise more if you need...
