Dame Deborah James has lost her battle with cancer at the age of 40, her family have announced on Instagram.
The mum-of-two, who launched a fundraising page called Bowelbabe to raise money for Cancer Research UK, was diagnosed with stage 4 bowel cancer just before Christmas 2016, when she was aged 35.
She raised millions in the first couple of weeks of the fundraiser being launched and in the wake of her passing, it surged past £6.77million.
