Well-wishers have exceeded their fundraising target in memory of a brave schoolboy whose life was cruelly cut short at the age of 15.

Described by his family as a "true fighter", George Hughes suffered two heart attacks and endured complex surgery before he sadly passed away in August.

Now fittingly "George's Army", led by his mum Jo Brazill and her close circle of friends, are embarking on a mission to raise money for a children's cancer charity.

And in the run-up to the London Winter Walk half marathon tomorrow (Saturday), they have collected more than £8,600 – beating their £7,675 goal – thanks to quiz nights, karaoke sessions, raffles and the proceeds of Christmas school and church fairs.

The challenge for Young Lives vs Cancer is all the more poignant to Jo as she was undergoing radiotherapy for breast cancer at a London hospital while her son was being treated nearby at Great Ormond Street.

Now in remission, the 40-year-old mother-of-three from Walderslade thanked the scores of generous people who have already donated to the cause.

She posted on social media: "We are overwhelmed with the love and support shown from our friends and family who have been truly amazing.

"They have come together to create some brilliant fundraising events which have done George's Army proud.

"We really appreciate all the hard work and are truly grateful."

Jo was able to cut short her medication so that she and partner James Hughes could be at his bedside where they stayed from March to August when George passed away.

Jo's mum stepped in giving up at work to look after their daughters Ellie, 19, and Kacey, 10.

George was born a healthy baby and alarm bells only started to ring when he started to get chest infections from about five months.

He underwent his first transplant when he was just two and his second at the age of 10.

George, a pupil at Victory Academy, Chatham, enjoyed school and in Year 10 was looking forward to focussing on his favourite subjects, art, media and history.
