"To me, this spirit of togetherness is a most important part of the Olympic ideal; and the British people can be proud of the part they have played in keeping the spirit alive.
"Many sports played in these Games have their historic roots in this country; and as a nation we have an abiding passion for sport, as well as a tradition of fair play and a good-natured sense of fun."
