Have been watching a few episodes & noticed they've been cut. "The Permissive Society" was on yesterday & some dialogue at the end of the episode about Rita's brothers getting out of the car was removed, nothing offensive was said ( unless you count "big buggers" ), so presumably it was done to fit the schedules.
"Food Glorious Food" had the dialogue about Pakistani's eating cats (!) taken out. It's a travesty that shows are butchered in this way.
