Pauline won Best TV Comedy Newcomer at the British Comedy Awards in 1990 for her role in Birds of a Feather, which would later return to screens in 2014.

However, the actress is now set to "step away from all commercial and professional duties" to spend time with her family.

The TV producer, who has been married to Pauline since 1996, released a statement, as seen by the Mail Online.

It read: "It is with a heavy heart that I announce my wife Pauline's decision to step back from all professional and commercial duties due to her diagnosis of Dementia in 2021.

"Pauline has been an inspiration through her work in the film and TV industry, her charity endeavours and as the founder of the very successful Pauline Quirke Academy of Performing Arts (PQA).

"Her talent, dedication, and vision have touched countless lives and will continue to do so through the legacy of her work and through PQA where her vision and guidance has facilitated many young peoples' progression and interest in the Arts and enhanced their self-confidence."

"Demonstrating her acting versatility, she also starred or appeared in more than 60 TV and film productions, including Carrie's War, North and South, Casualty, Cold Blood, Thieving Headmistress, My Family, You, Me and the Apocalypse, and of course Emmerdale.

"During her epic 50 year career, Pauline has been nominated for many awards, including Best TV Comedy Actress in the British Comedy Awards, Best Newcomer in the British Soap Awards and has received multiple nominations for Most Popular Actress and Most Popular Comedy Performer in the National Television Awards.

"Her acting career has now come to a close, but Pauline Quirke Academy of Performing Arts (PQA), with its network of approximately 250 academies and over 15,000 students across the UK, remains robust and will continue to operate as normal in accordance with Pauline's ideology.

"We kindly request privacy and understanding for Pauline and our family during this difficult period. For the time being we will not be engaging in interviews or making further statements, since Pauline just wants to spend time with her family, children and grandchildren."

Pauline was born in Hackney in 1959 and shares a son with her husband Steve.

She has a daughter, Emily, from a previous relationship.

Hilary Evans-Newton, Chief Executive of Alzheimer's Research UK, said in a statement on Tuesday: "We are saddened to hear of Pauline's diagnosis and send our best wishes to her, Steve and the wider family.

"The family should be praised for making the brave decision to make her diagnosis public, which will not only provide more freedom for them, but also raise such vital awareness of the condition.

"We're so grateful that Pauline and Steve have pledged to support our work when the time is right. We look forward to working with them to raise further awareness of dementia and funds for research."
