Help! I have pulled my air vent knob off

[pmp4]

I was bored one day and ended up pulling the centre knob of the right hand vent nearest the drivers door. I have tried pushing it back but spindle goes back into the vent. I am guessing I will have to remove it. I can't see how it comes off or how how to remove the slver dash trim around it. Any ideas anyone?

My car is a uk 2001 Cooper
