Clutch problem on 2009 Defender 110 County

Hi Everyone

I was driving my defender 110 today when pulling up at the lights & clutch to change gear the pedal lost pressure and stayed down, I checked fluid, topped up but no difference. The landi has 59000 miles on and i have had no other clutch problems to date.
Can anyone shed any light what the problem may be?

hey there, possibly a duff slave cylinder. Is there any liquid leaking from under Neath? Near the bell housing area?
