After a huge struggle with seized bolts I got my slave cylinder changed last weekend, bled the system through, lots of new fluid added, everything tightened up, road tested and master reservoir topped off.

On the way to the MOT station this morning, when changing from 1st to 2nd, when I released the clutch the pedal was light and the clutch itself hadn't released (i.e. I'm sitting there revving but going nowehere), I pumped the pedal in and out and changed from neutral to 1st a few times and after 6/7 attempts the clutch went firm again and off I went.

What could this be? It appears back to normal now but I'd hate it to go on a busy road/motorway, god I hate intermittent problems!

This happened to me shortly after I bought mine, put a new slave cylinder in and it worked for a few minutes then it went back to its old ways.

Changed the master cylinder (I'd bought both just in case) and all was fine. Bad news: master cylinder is more expensive. More bad news: it's also more of a pain to change. On mine one stud was in the engine bay, the other in the footwell.

Definitely no leaks, pretty sure its bled properly, bled it until fluid was coming out with no air bubbles that I could see, pedal felt very firm. Might do it again tonight just in case, can't do any harm I guess.

Is there any easy way to see if the master cylinder is gone? when I pushed the piston on the slave it was apparent as fluid sprayed out of the rubber boot, is the master similar?

An easy check would be to get someone to sit in the drivers seat and push the pedal.

Watch the slave cylinder push out.

If it then starts to slowly return back, somethings leaking.

I assume you mean if it slowly returns back whilst the pedal is still depressed? I'll try that also. I marked where the fluid was filled to on the reservoir so I'll see if it's dropped any since the weekend.

One bit of good news, MOT station just called and it couldn't have played up whilst they had it as it passed!
