Hi, I have a 2006 LHD Panda 4x4, the radio has suddenly stopped coming on or going off with the ignition, it works ok using its own on/of switch. Any ideas would be gratefully received.

Is it the standard radio?

Yes it is the standard radio. In my experience of fitting car radios there has always been a separate fuse for this operation, but where? I don't have the key to remove the radio and check.

Check the manual. Can be found in the downloadsection of this forum.
It has to do with when you switch the radio on. Wake-up on ignition is done by Can-bus signal.

Are you sure it isn't just the delayed-off feature?
It is set by the menu on the radio and it isn't that hard to set it or reset it by accident.
Otherwise as A3jeroen says, it's a CANBus controlled operation so pretty sure it's not a fuse-related problem.
