Coronation Street star Helen Worth, known for playing Gail Platt, is set to leave the popular soap opera after 50 years, ITV announced.

At the end of this year, the 73-year-old will walk along the cobbles one last time after she celebrates her golden anniversary next month.

Worth will leave the show after a “major storyline for the Platt family” which will start being filmed next month.

Worth said: “This year felt like the perfect time to leave the show after celebrating 50 years in the most wonderful job on the most wonderful street in the world.

“I made the decision at the start of the year and spoke to the producers who were very kind and understanding.

“I have been truly blessed to have been given the most incredible scripts week in week out, and to have worked with fantastic actors, directors and a brilliant crew.

“The past 50 years have flown by and I don’t think the fact that I am leaving has quite sunk in yet.”

Coronation Street executive producer Iain MacLeod said: “The words ‘legend’ and ‘icon’ get used a lot these days but they genuinely do apply to Gail and to Helen Worth.

“However, given her humility, I know Helen won’t thank me for saying so.

“In Helen’s hands, Gail has been a huge part of Coronation Street for five decades and at the centre of some of the most memorable storylines – often deriving from her catastrophically bad luck in choosing husbands.

“Her ill-fated marriage to Richard Hillman was one of the most ground-breaking stories in soap history and cemented Gail’s already established status as one of the Corrie greats.

“As the matriarch of the Platt clan, her affectionately prickly relationships with her kids and flighty mum Audrey epitomise what makes the show great: complicated family dynamics brought to life impeccably by Helen’s dramatic and comedic chops, alongside those of her fictional clan.

“Gail has given us countless hours of entertainment but it should also be said that Helen herself is a consummate professional and a thoroughly good egg.

“Everyone connected to the show will miss having her around the place just as much as the viewers will miss having her on their screens and we wish her all the very best for the future.”
