Scots actor John Hannah says he believes there should be a right to assisted suicide after watching his 84-year-old mum battle dementia.

The Four Weddings and a Funeral star told the Radio Times that he had been hit hard by the recent decline in his mum Susan’s health.

Assisted suicide, which is currently illegal in the UK, has been at the centre of a debate over whether it should be legalised in the UK.

In an interview with the Radio Times he said: “My mum’s got no quality of life whatsoever.

“If someone said you can let her go now, my sisters and I, we would say, yes do that.

“She can’t say it now, now the dementia has developed.”

The Scots star’s dad died last year and his mum is living in a care home.

He added: “She really doesn’t want to be here.

“She’s been in a home for a good four years. And before that she was done with life.

“Maybe there comes a time when you are done with that natural cycle.

“It’s been quite a traumatic couple of years. My dad died at the end of last year, we are selling the house, my mum’s in a home so I have been going back and forward with that.

“It’s horrendous.

“My dad, we wanted him in a home and he resisted and resisted, and he fell down the stairs and that was it.

“I am hoping by the time we get to that age there will be an assisted exit programme.”

Hannah is currently starring in Marley’s Ghosts, a supernatural comedy on UKTV channel Gold.
