A charity set up in memory of a teenager from Cambridgeshire has celebrated its first anniversary.
Liam Fairhurst from Soham died of cancer four years ago. He was 14-years-old and had raised hundreds of thousands of pounds for charity.
His family has continued his fundraising efforts by setting up the Liam Fairhurst Foundation, which supports children with cancer and other serious conditions.
Last night, they held a reception at 11 Downing Street where they were congratulated on their work by the Chancellor George Osborne.
It was Liam's younger brother Callum, now 16-years-old, who founded the charity. He has been involved in numerous fundraising activities, completing an 800-mile charity bike ride earlier this month.

"We are immensely proud of Callum, who has managed to turn negatives into positives. He arranged the whole event by himself and managed to organise the kind presence of Mr Osborne, despite a busy schedule.
"He has been the driving force behind the charity and his hard work has been recognised by all involved.
"Liam would be very proud of Callum's hard work in ensuring his fundraising and memory continued in such an appropriate way."
The event featured several speeches from the family and other supporters of the Liam Fairhurst Foundation.
There was also a speech from Stephen Sutton - an 18-year-old who has an incurable form of cancer. He has created a 'bucket list' and one of his ambitions was to do some public speaking.
There were around 80 guests at last night's event, including Cambridge MP Julian Huppert and various other supporters of the Liam Fairhurst Foundation.
