Great Britain's Paralympic gold medallist Jonathan Fox has praised his compatriot Josef Craig for smashing his world record in the pool at the Aquatics Centre this morning.
The teenager managed to enter his name in the record books after winning his heat in the S7 400m freestyle in 4:45.79.
"I went into the race to try and qualify first but you can't really count your chickens when you're out there on the blocks," said Fox. "Josef is 15 and has been training really well so hats off to him for breaking that record by so much."
Fox managed to win his own heat and will go up against Craig in the final this evening.
