Oliver claimed her maiden individual field gold with a 50-45 victory over Jessica Tomasi of Italy in the final to cap off what has been an emotional competition for the Briton following the recent death of her grandmother.

"It’s really emotional - I just can’t really believe that it has happened," she said. 

"I wasn’t really thinking about the end result, I just wanted to shoot nice shots – and that was really all the way through the week.

"It’s emotional because my grandma passed away recently and she was a field archer. 

"So it’s nice to be able to do it for her."

Bronze in the women's competition went to Joanna Razsa of Poland, who earned a narrow 40-39 triumph against Germany’s Daniela Klesmann.

In the men's event, Ellison, the favourite, overcame Germany's Sebastian Rohrberg 59-52 to win the gold medal.

Frenchman Jean-Charles Valladont, the Olympic silver medallist, did enough for the bronze as he beat Italy's Marco Morello 57-56.

Elsewhere on a packed day of finals at the World Archery Field Championships, Steve Anderson built on the success of compatriot Ellison as he secured gold in the men's compound tournament with a 66-65 victory against Denmark's Stephan Hansen.

The US were denied bronze, however, as Dave Cousins was beaten 66-65 by Norway's Njaal Aamaas.

Erik Jonsson of Sweden sealed the men's barebow crown thanks to a 57-54 triumph over Spaniard David Garcia Fernandez, while team-mate Martin Ottosson rounded off the podium with bronze by defeating Australia's Michael Fisher 51-42.

Chantal Porte of France cruised to gold in the women's event, beating Eleonora Strubbe of Italy 43-37 in the final.

Sweden's Lina Bjorklund comfortably overcame Miyuki Maruyama of Japan 49-37 to win the bronze medal.
