15 year old Ian Ford from Armadale took home the gold medal after competing in front of thousands of spectators at the International TaeKwon-Do Federation (ITF) tournament in Dublin.
Ian battled through 6 rounds of competition before defeating his Spanish opponent in the final.
Provost Tom Kerr invited Ian to West Lothian Civic Centre where he was presented a civic gift to mark his achievement.
Provost Kerr said: "This is an outstanding achievement in a very physically demanding sport. Ian's hard work, determination and talent have taken him to the pinnacle of Taekwondo as a sport so it only correct that his success should be recognized. The fact he is the first Scot to have become world champion in 20 years demonstrates how unique a triumph this is so well done to Ian and hopefully this isn't the last medal he brings back to West Lothian."
