TOPIC: Siezed clutch

My clutch has siezed after the winter lay-off and I can't select any gear. The slave cylinder is ok and is operating the lever so the problem is the clutch itself. I have tried putting the car in gear, pressing the clutch pedal and the brakes, and turning the key to try and free it off, but no success. any ideas as twhat to do next?

Panic over, managed to free it off after recharging the battery and selecting fourth. Slight bang and now ok.
