Stretton, the youngest athlete in the field, triumphed 137-124 to take top honours in the new Paralympic category.

Both she and Frith were joined on the podium by fellow Briton Vicky Jenkins, who beat South Korea’s Kim Ok-Geum 125-124 in the bronze medal match despite having been in hospital in the build-up to the competition with a neurological problem.

It is only the second time in history that an archery podium has been monopolised at a Paralympic Games.

"It feels just amazing," said Stretton.

"We’ve had a podium like this in international competition before and it’s just the most amazing feeling ever.

"I was pretty nervous - I felt like I was taking a step for the youth that can be in Para-sport and showing them that it can be done and it will be done."

Frith recovered from her disappointment at missing out on gold to help Britain claim the mixed team W1 title alongside John Walker.

The top seeds edged out Kim and South Korean team-mate Koo Dong-Sub to win the final 139-129.

"It shows that we are the best in the world, particularly in the W1 category," Frith said.

"We're streets ahead of everyone else.

"The hard work we put in, week-in week-out, with the funding, we’re able to practice our mixed team, and that’s why we’re so slick, so comfortable."

The medal was Britain’s sixth of the Games in archery and lifted them to the top of the sport’s standings with three golds, two silvers and one bronze.

Czech Republic’s David Drahoninsky and Sarka Musilova took bronze by virtue of a 137-129 victory over the United States' Jeff Fabry and Lia Coryell.
