The 49-year-old’s devastated family revealed to the Yorkshire Evening Post that his battle had simply got too much for him and he had come to the heartbreaking decision to withdraw from all treatment.
On Friday he was transferred from St James’ Hospital - where had been since March 31 last year - to St Gemma’s Hospice where he spent his final hours surrounded by his family.
Paying tribute to her "soulmate", his wife Sue, 63, who has been with Jason for over 20 years said his death was "so peaceful".
