No probs :D Yep, was clutch - the little tin can on the firewall.
That's what I ended up thinking too - from my little knowledge of all things mechanical, after being pointed in the right direction by PhilipA & Wagoo. Prior to that, I had thoughts of the gearbo & clutch being pulled apart, etc!
I had a look but couldn't see any leaks from the master cylinder OR the slave cylinder though. Maybe it's just a blockage in the pipe - who know when the oil was changed last!
