The brother of cancer charity hero Stephen Sutton has achieved a first-class honours degree after sitting his final university exams following his sibling's death.

In a statement posted on the Stephen's Story Facebook page, Stephen's mother Jane confirmed that Christopher Sutton had averaged around 87% during his four-year course in mathematics and mathematical physics.

Mrs Sutton, from Burntwood, Staffordshire, wrote: "Everyone knows how amazing Stephen was.

"However, I also have another amazing son, Christopher, who has been studying for the past four years at University College London.

"Yesterday he got his results and he will graduate with a first-class honours degree."

Describing Christopher's achievements as incredible, Mrs Sutton added: "What makes this all the more impressive is that Chris was sitting his finals when Stephen was admitted to hospital in April, then had to sit the remaining three after Stephen passed away.

"Congratulations Chris you're a star, or 'awesome' which is how Stephen would have described you."

A JustGiving page set up by Stephen, who died aged 19 in May after a three-year battle against multiple tumours, has so far raised £4,233,622 for the Teenage Cancer Trust.
