Formula One world champion Lewis Hamilton has paid an emotional tribute to Harry Shaw following the death of the five-year-old, whose battle with cancer inspired him to victory at the Spanish Grand Prix.
The youngster died on Saturday but "fought to the very end", his family said as a charity fundraising page saw donations climb to more than £235,000.
Hamilton was among a number of stars from the sporting world to lend support to Harry's Giant Pledge.
Five-time world champion Hamilton had been alerted to the youngster's plight after he received a good-luck video message ahead last month's race in Barcelona.
The British driver dedicated his win in Spain on May 12 to Harry, while Mercedes sent the trophy and one of their cars to the family's Surrey home for them to enjoy.
Following the news of the five-year-old's death, Hamilton wrote on Twitter: "Harry, thank you for being such a positive light to us all. You're so brave and the world will miss you dearly. Thank you, friend and inspiration".
England cricketer Jos Buttler, former England footballer Gary Lineker, and tennis star Novak Djokovic were among other big names to speak about Harry's illness on social media.
His parents, Charlotte and James Shaw, set up the fundraising page for the The Royal Marsden Cancer Charity after Harry was given just seven days to live on April 29.
He had been diagnosed with Ewing's Sarcoma, a rare bone cancer in August 2018, aged just four.
In a statement on social media, Harry's family had earlier said: "His pain and suffering is over. It is impossible to imagine life without Harry and the hole he will leave in our lives.
"We are SO proud of Harry and everything he achieved in his life and the legacy he has created to help others.
"We miss him so much."
