I doubt for sure if anyone knows if they are off spring from an existing uk nest or are incursions that have successfully managed to hitch a ride on vehicles/boats coming over from France.
They are certainly here to stay if incursions aren't dealt with, once a nest or two complete a full cycle then expansion will begin. Next few years will tell if efforts are working but NBU will have their work cut out to keep pace me thinks. At the mo they are probabaly working very hard with few resources.
