I've reported it to the police, and changed the status to stolen on immobilise.com. In the meantime, please let me know if you see it somewhere, either in person or for sale online.
It's a blue Roberts touring bike, with my name ("John Kirk") painted on the side of the top tube. It has racks fitted at front and back, and a 2-leg stand. Frame number 100613.
