Dame Barbara Windsor and her husband Scott Mitchell have urged the Prime Minister to "sort out" dementia care, after they were named ambassadors of Alzheimer’s Society.
In an open letter, the pair have asked Boris Johnson to use the autumn spending review to address the “devastating state" of care those with the disease receive.
“Our experience is of a care system that too often doesn’t care – one that is completely inadequate, unfair, unsustainable and in dire need of more money,” it read.
The actress is urging others to sign the letter, which is calling for an end to the "social care crisis".
Dame Barbara, known for her roles in the Carry On films and EastEnders, was diagnosed with the Alzheimer’s disease in 2014.
The condition, which is a form of dementia, is a progressive decline in brain functioning that affects memory and thinking skills.
The couple’s ambassadorship was announced today, on Dame Barbara’s 82nd birthday.
She said: "I am absolutely delighted to become an ambassador for this wonderful charity, who are helping so many people living with dementia... like me.
"We're lucky to have amazing support but my heart goes out to the many, many people who are really struggling to get the care they so desperately need.”
Mr Johnson, who Ms Windsor has met on several occasions, promised a “clear plan” to address the social care issue when he first entered Number 10 last month.
In his first speech as PM he said: “I am announcing now, on the steps of Downing Street, that we will fix the crisis in social care once and for all with a clear plan we have prepared to give every older person the dignity and security they deserve.”
