Enfield-based North London Shotokan welcomed Ticky Donovan, the English National Karate Squad director, to the club last week.
Sensei Donovan was helping run a course, which was only open to some of the sport's top performers. He was able to offer expert tuition on an individual basis.
After the course, which lasted nearly three hours, Sensei Donovan had his photograph taken with the students and signed autographs.
He is now off to train the English squad for the WKF European Championships in Norway.
North London Shotokan train at Enfield Island Village.
