The show is half way through its first series and Channel four has already commissioned a second series because it has been a huge hit with the viewers.
The first episode opened with a total viewing of 2.5 million of viewers – 1.6 milion who watched it live while a further 900,000 had recorded it or watched it on catch-up or on demand.
The Sinn Féin MP said: “Every week well over a million people are tuning in to watch a good-natured comedy about my native city.
“When I travel throughout Ireland, and to London, the reaction of people to the show’s portrayal of Derry is uniquely positive.
“This success is shining a positive light on the rich cultural heritage of Derry City, while raising the profile of our city, sure to encourage tourism and engagement.
“I would like to congratulate and commend Lisa McGee, the show’s creator and a Derry native, for her achievement and immensely positive contribution in bringing Derry to an international audience on a Thursday night.”
