Stephen Sutton, the teenager who raised more than £4m for charity.
More than 7,000 people have attended a vigil in Lichfield Cathedral to pay their final respects today.
Instead of the traditional minute’s silence, a moment of celebration will be held at 11:00 BST.
Stephen’s mother, Jane Sutton, has called on people to take part in a social media “thunderclap” at the same time – a message posted simultaneously on Facebook and Twitter – in memory of her son. The message is #ThumbsUpForStephen.
The charity Stephen had been supporting, The Teenage Cancer Trust, said nearly 15,000 people had signed up to take part.
