When the ignition is off the side lights stay on in normal circumstances.
Now when the ignition is off the lights are off too!
Is this a fuse/relay problem?
If so which/what is likely to be the cause?
Cheers guys.
Side/parking lights problem

Fuse 22 feeds the left hand sidelights and fuse 23 feeds the right hand sidelights and instrument lights.
Both these fuses are permanently live and feed via seperate wires to two independant switches in the lighting switch, and from there by seperate wires, via the check control modules, if fitted, to the sidelamps themselves. There is no connection to the ignition circuit at all, so I can't think of anything that would fit your symtoms.
Sure you'r not confusing the parking lamps at the front, (small bulb at top of headlamp unit), with dim dip driving lights, ( dipped headlamp bulb running at reduced brightness ), which only work with the ignition and sidelight switch on?

Its definitely the parking lights.
They used to come on when the ignition was off, but now they dont.
They work when the ignition is on though!
I may try swaping a few fuses round to see what difference that makes, if theres something dodgy with the fuse itself!

Point is, it's two completely independant circuits for the sidelamps, and you've an identical fault with both of them at the same time.
First check is to see if both fuses, ( 22 and 23 ), are live at all times. Use a 12V 5W or 10W lamp connected to two pieces of wire to check, not a multimeter. Connect one wire to the car body, and touch the other against the wire link in the fuse. If you have the OE fuses, you should be able to connect without removing the fuses.
