Williamson will be competing alongside two-time Olympian Naomi Folkard and Amy Oliver, who will be hoping to secure her debut spot at London 2012 at the test event, and the trio will be in confident mood of building on the silver medal they picked up at the Commonwealth Games last year.

Simon Terry, Larry Godfrey and Alan Wills, who competed together in Beijing in 2008, will be participating in the men's trio.

Terry is a double Olympic bronze medallist, and has re-established himself in the sport after a 10 year absence from the, and Archery GB performance director Sara Symington warned the archers that there is a lot of work to do to achieve selection for London next year.

"The six archers who will be taking part at Lord's have been selected on the basis of how they have performed this year, but there is still a lot of hard work ahead before anyone can secure their Olympic place," she said.

"The archers who hope to represent Great Britain at next year's Olympic Games will have to take part in a tough selection process.

"The important thing to point out is that everyone aspiring to claim a place at Lord's will have a chance if they achieve the required scores to be invited to the selection shoots."

The tournament gets underway on October 3 and is an official World Archery tournament, with the men's team tournament taking place on the second day and the women's competition on the third.

Men's and women's gold medal matches will take place on October 9 and 10.
