It was not an in-flight refusal and subsequent diversion!
I was working that evening and feel that the media have misled the public by failing to divulge all parts of the story (something they frequently do). The plane was running much later than expected and for whatever reason Southampton were unable to stay open. As a result the flightplan was changed to Bournemouth at least 30 mins before the a/c got airborne giving plenty of time for the ambulance to get there before it landed.
