She appeared with David Hasselhoff and Michael McIntyre. She criticised the Doctor's TARDIS, saying it was "just the same thing again", "an appearing, disappearing, blue telephone box". The Doctor apologised, explaining to Dermot that she was now Prime Minister. He said that in "the Holden Years" she was notorious for pressing "that big red button", which she did to the Doctor.
