The World Conker Championships is investigating cheating allegations after the men's winner, David Jakins, was found with a steel chestnut in his pocket.

David Jakins, 82, won the annual title in Southwick, Northamptonshire, for the first time after competing since 1977.

Jakins, who was responsible for drilling and inserting strings into other competitors' chestnuts, denied using the metal variety in the tournament.

Alastair Johnson-Ferguson, who lost in the men's final against Jakins, expressed suspicion of foul play after his conker disintegrated in one hit.

Kelci Banschbach from Indianapolis defeated the men's champion in the grand final, becoming the first American to win the competition.
