A woman who campaigned to end her own life because she was in constant pain has died in Switzerland’s Dignitas clinic.

Jackie Meacock, from Brighton, suffered from the neurological disorder dystonia and took her own life at the clinic with her family including three daughters beside her.

Previously Mrs Meacock had created a video diary for BBC South East calling for assisted suicide to be legalised.

In it she said: “If I was a dog, you would put me down.”

She died on September 13.

People with dystonia suffer sustained muscle contractions which cause twisting and repetitive movements or abnormal postures.

Her daughters, Nina Sloper, Donella Preisler and Caron Gill, said their mother had wanted to die at home.

They said while they accepted there were people who would not support their mother’s choice they did.

In a blog post Mrs Preisler said cases such as that of her mother should be considered carefully.

She said: “We’re not saying it should be legal for a doctor to kill you, but it should be de-criminalised for those in exceptional circumstances.

“Each case should be considered on an individual basis, much the same as Dignitas do. The issue is about choice.

“What if that person doesn’t want to live with their disability? What if that person doesn’t want to live with the constant agonising pain that accompanies the disability?

“Who are we to insist and play God by saying you have to keep living regardless of how you feel because we don’t think it’s right to end your life and your suffering?

“The biggest tribute I can give my mum is to carry on with her campaign to bring the debate out into the open.

“Death is something we will all face, it’s the one certain thing in life, some of us would just prefer to choose when we go and not be at the mercy of our pain and suffering.”
