The government should support and fund choirs to help dementia sufferers cope with their fading memories, Line of Duty actress Vicky McClure has said, as she speaks of caring for her grandmother.

McClure is hosting new television show Our Dementia Choir, which offers those with dementia music therapy as they train to perform as a choir in front of an audience of 1,000 people.

The Line Of Duty star joins forces with specialists from the fields of medicine, music therapy and performance for the BBC One two part series.

"The Government doesn't put enough funding into research. I am passionate about looking into that," McClure said.

"I want to know what's being done on that side of things.

"The funding is the hardest part, to have the choir running all the time, they're not cheap. It's free to sing, but to have that routine and providing tea and coffee and somewhere to do it, it costs money.

"It can be cheap and manageable, but it's not free. (We) need the backing of councils and the Government."
