Personalities including Dame Dame Julie Walters, Dame Dame Judi Dench, Stephen Fry, Brian Cox, Dame Dame Harriet Walter, Luke Evans, and Stephen Tompkinson are backing Alzheimer's Research UK, supporting a petition calling on the UK government to 'keep its promise' to double dementia research funding.

Mamma Mia! star Walters, whose grandmother suffered from vascular dementia, said 'There is an urgent need for research to bring about life-changing treatments for people affected by dementia. With the tragic impact Covid-19 has had on those with the condition, the funding promised by government is more critical now than it ever has been and it’s clear the public agrees. I’d urge everyone to sign this petition, so we can make it clear to government that we will not let their promise be cast aside'.
