Mavis Williams says watching her grandson Adam Peaty compete has given her a "new life".

"I've loved every minute of it," she said, "it's a tremendous achievement what he's got, and all the family are proud of him but it's nerve wracking for me."

Speaking to 5 live Breakfast, Mavis described how she "screamed" for Adam last night as he competed in Rio, but that her neighbour "didn't mind".

Peaty broke his own world record as he reached the 100m breaststroke final.
