The widow of former Durham Police and Crime Commissioner Ron Hogg has told BBC Breakfast she now supports assisted dying and is calling for a change in the law.
Mr Hogg campaigned for it to be de-criminalised before he died in December, aged 68, months after he was diagnosed with motor neurone disease.
Having previously been against such a move, his wife, Maureen, said her views had changed:
"His condition was deteriorating almost by the day. At that point we were just trying to get through each day.
"To see him cry, to be in that situation, was heartbreaking and that's something he had to live through and the memory is something I have to live with for the rest of my life.
"It's not what I would've wished for, so yes, I have changed my thinking."
It is illegal in England and Wales to encourage or assist a death and it holds a prison sentence of up to 14 years.
The Royal College of GPs is set to announce its stance on the issue later.
