A closely fought contest would see Brett and Johnston triumph 7-6 in the opening end, but their rivals hit back to win the second 9-7.

Brett and Johnston would level the scores by winning the next end 2-1 to take the match into a tie-breaker.

The pairing held their nerve to ultimately triumph in the tie-break and secure the world title.

In the men’s singles, Greg Harlow won an all-English second round match 9-3, 10-11, 2-1 against James Rippey.
