The Prime Minister has praised a young athlete who helped create a magical moment for the country when she lit the Olympic cauldron.
Katie Kirk, 18, met David Cameron when he visited Northern Ireland. He described her as an inspiration.
Mr Cameron said: "The idea of all those petals (of fire) coming together...it was extremely beautiful and moving, it was also a brilliant feat of engineering."
He told an audience in Coleraine the notion of having young athletes light the cauldron was inspired.
He addressed Kirk: "It was a beautiful, magical moment for our country and it was great that you were part of it."
Kirk recalled the moment she lit the fire in front of millions.
"It felt really good, it was a brilliant experience," she said.
"The atmosphere was emotional and electrifying really."
Thousands of people crammed into the stadium in East London for the spectacular ceremony, with many millions more around the world watching on television.
Kirk, from Holywood in Co Down, was nominated by Olympian Dame Mary Peters, who handed her the flame in a moving gesture. She was one of seven young athletes to light the cauldron.
