Actress Stephanie Cole, known for roles in Tenko, Open All Hours and Coronation Street, has died aged 84.

A statement from her agent John Grant, issued on behalf of her family, confirmed the actress had been living with Alzheimer’s for several years.

“Stephanie was an extraordinary talent whose long and distinguished career included many iconic performances in theatre and television,” the statement read.

“She brought joy to millions through her many much-loved roles in sitcom and drama. She will also be remembered for her tireless work supporting mental health charities.”

Solihull-born Cole, who trained at Bristol Old Vic Theatre School, after making her stage debut at the age of 17 – playing the 90-year-old medium Madame Arcati in Noel Coward’s Blithe Spirit.

She went on to enjoy a lengthy career that spanned TV, radio and film and was perhaps best known for playing Dr Beatrice Mason in the 1980s BBC wartime TV drama Tenko.

The series chronicled the lives of British women in Singapore after the Japanese invasion and their consequent confinement in a Japanese prisoner of war camp.

Cole, in her breakout role, played a doctor who struggled to look after the health of the women, opposite Ann Bell and Claire Oberman.

During this same period, Cole also played the moody customer Mrs Delphine Featherstone, aka “The Black Widow” in the Ronnie Barker-starring Open All Hours.

She would go on to win the award for best TV comedy actress for her part as the sharp-tongued photojournalist Diana Trent in Waiting For God.

But she cited her earlier performance as Muriel in Alan Bennett’s monologue Soldiering On, alongside Maggie Smith and Julie Walters, as one of her proudest moments.

Her stage highlight, by her account, was in a West End production of A Passionate Woman.

Cole also played the aunt of Martin Clunes’s titular character in the ITV medical drama Doc Martin.

Her other notable roles included Keeping Mum, and the BBC Radio 4 sitcom Cabin Pressure – alongside a fast-rising Benedict Cumberbatch – as Carolyn Knapp-Shappey.

“One of the joys of my character was how strong and feisty she is: she had the upper hand over the men, for the most part,” she told the Guardian, external in 2018.

“Carolyn told it like it was and took no [rubbish]. We’ve all met women like her. She was very easy to put on, and I confess perhaps there’s a little of her bossiness in me.”

She also appeared in Coronation Street as Roy Cropper’s mother Sylvia Goodwin, which won her another comedy prize, in her 70s, at the 2012 British Soap Awards.

Cole reprised her earlier role in the 2010s reboot Still Open All Hours, opposite David Jason, and also appeared alongside Suranne Jones in Gentleman Jack.

On Halloween 2018, she also guest starred in the live episode of Reece Shearsmith and Steve Pemberton’s Inside No.9, titled Dead Line.

The actress’s stage work included Driving Miss Daisy, Talking Heads, Noises Off, A Passionate Woman and King Lear.

Her last major TV role was appearing opposite Greg Davis in his BBC comedy series The Cleaner in 2021.

Cole was married twice – first to playwright and theatrical fight director Henry Marshall, whom she divorced in 1998, and next to fellow actor Peter Birrel, who died in 2004. She is survived by a daughter, Emma Battcock.

Cole was made an OBE in 2005, for her services to drama, the elderly and mental health charities.
