ALEX Callan is a horse chest nut. And his devotion to the ancient game of conkers has led to him being crowned supreme champion of the world. He has our sincere congratulations.

The Selby sales manager is determined that his all-conquering achievement will not change his life. We wish Alex luck with fending off the conker groupies who will demand to see him stringing and swinging every time he steps out of his door.

There are new challenges ahead. The world champion will be looking to London 2012. By then, conkers may well be an Olympic sport.

A gold medal would be the ultimate prize - but it will be a tough nut to crack.
