David Cameron said "a very, very bright light has gone out" following the death of cancer patient and charity fundraiser Stephen Sutton this morning.
Calling Stephen "deeply inspirational", the Prime Minister said he could "hardly think of anyone I've met with such a zest for life and such a belief that you can get things done, and who wanted to live every minute".
"He was determined not to be cowed by it and to make the most of every single moment on this Earth, and he absolutely did that," Mr Cameron continued.
"I think that's why he created this phenomenon, not just here in the UK, but right around the world".
The Church of England has offered Lichfield Cathedral as a funeral venue to the family of inspirational teenager Stephen Sutton.
Stephen Sutton was "a credit to humanity" whose "spirit lives on", say this morning's front pages.
