British taekwondo fighter Jade Jones cruised into the quarter-finals of the women's under-57kgs with a 15-1 victory over Serbian Dragana Gladovic at ExCeL.
Jones, like all home nation taekwondo fighters seeded fourth, immediately went on the offensive, scoring with a kick to the body, however it was even at 1-1 after the opening two minute round. The Wales fighter opened up a healthy 7-1 lead at the start of round two following a flurry of kicks, including one to the head.
Jones - Youth Olympic champion two years ago and world silver medallist in 2011 - scored another big head shot to lead by 10 heading into the final 60 seconds, before ending the contest early with a 14-point margin as she landed again.
The Briton will take on Mayu Hamada of Japan in the last eight on Thursday afternoon, after she edged past Croatian fifth seed Ana Zaninovic, who had a head kick score at the buzzer correctly wiped off on video review for holding.
Next up for Team GB is Liverpool's Martin Stamper in the under-68kgs against Erick Osornio Nunez of Mexico.
There was little to choose between the fighters after a scoreless first round.
Stamper picked up a warning for moving off the mat as the contest continued to sit on a knife-edge with no kicks or punches from either man registering.
With a minute left, Stamper finally hit the target - and moved 4-0 up after a head kick made minimal contact. The score was immediately challenged by the Mexican corner, but the appeal was rejected on video review.
Osornio Nunez closed the gap after another warning for Stamper, but a body shot by the Liverpudlian saw him close out the contest 5-2 as both Team GB fighters moved into Thursday afternoon's session.
