A statement issued by Channel 4 and producers Studio Lambert on behalf of her family said they were “extremely saddened” to share the news.

She died in hospital at the weekend with her family by her side, it said.

“Beloved mother, grandmother, great-grandmother and dear friend to many, Mary, who worked in the hospitality trade, had been married and widowed twice.”

The pair “became instant fan favourites due to their brilliantly witty and often cheeky moments”, the statement added.

“Mary will be sorely missed by the entire Gogglebox family, cast and crew.

“Our love and thoughts are with Mary’s family, friends, and Marina. The family have asked for privacy at this sad time.”
