I set off to work for a night shift in my van (1.7 LHD T25 G reg) and stopped off at the shop on the way to get some butties and Red Cow

When i returned to the van and turned the key a nothing happened bar the ignition lights etc coming on.
But the Starter motor didn't even try, there's no sound of it working at all.
Any ideas if this would be an ignition problem or if it would be the started motor goosed??
Cheers
