The 17-year-old from Doncaster was in scintillating form bringing an early end to his -78kg final bout against South Korean Yeong Rae with the score at 12-8.

This followed convincing victories in earlier rounds in which he beat opponents from Afghanistan, Chinese Taipei and Russia each within the three rounds by creating a seven point gap and before overcoming China in the semi-final. 

Cook said, “China and Korea are traditionally the two strongest nations so to beat them in the semis and finals is an absolute dream - I can’t stop smiling.

"I knew I was in good form from my earlier rounds but my match against Korea felt a breeze.

"Going into the final round at 10-8 I decided not to hang around and managed to score 2 points quickly to take it to 12-8 which means I automatically won and the fight stopped early.”

Liverpool's Bianca Walkden continued Britain’s rich vein of form by taking the 68kg silver medal in a tightly contested final, losing to her Tunisian opponent 4-3.

The 16-year-old beat competitors from France, Canada and Russia to reach the final but ultimately could find no way past the Tunisian who has already proved herself to be of world-class calibre by qualifying for the Olympics and winning the Beijing Test Event. 

The WTF World Junior Championships were the last major international event that British Taekwondo will send a team to before the Olympics in the summer where the British team have secured three out of a maximum four Olympic spots.

The squad to travel to Beijing is due be announced at the Korean Cultural Centre in London on Tuesday May 20.
