It won't Start

I haven't taken the car out in a while as the weather hasn't been up to it. This weekend I was called upon to use it as a prop in a photo shoot for the school teddy bear.

Went to garage to find I'd forgotten to leave the battery trickle charging - I think the electronic flasher is draining current somewhere (to earth of course!) so the battery was flat.

Unfortunately, jump starting wouldn't work either as the starter seems to be jammed. One for next weekend.
