2002 Other Renault Models remove steering wheel

Steering problem
2002 Other Renault Models Engine Size unknown Two Wheel Drive Manual 91000 miles

I have a renault traffic and the steering wheel is getting wobbly and I need to look at the retaining nut, however there are no visible screws behind the steering wheel to release the front of it so I can take the airbag out and its driving me mad how I can get to the main retaining nut, any ideas would be great!
