You should have put the policy on a "suspension" basis, where the policy is basically put on hold until it can be allocated to a replacement car.

What you will probably find is that the car caused damage to either property (wall, road, etc..) or to another vehicle and their insurance have probably gone to the MIB who have found that insurance is still on the Peugeot. So, as you have insurance on the vehicle still, you are next in line for them to reclaim their money.

As I say, Tony @ Greenlight would most likely be your best friend in this instance as my information will be a little sketchy @ best and will only be my own opinion.
