England could bag two gold medals from Sunday's Commonwealth Games squash doubles finals in Manchester.

One of them could go to Peter Nicol, who will bid to improve on the silver he collected from the singles by triumphing with Lee Beachill against Australia's Stewart Boswell and Anthony Ricketts.

The English duo booked their place in the final at the end of a fiery encounter with the other Aussie pair, David Palmer and Paul Price, which ended with the two teams having to be separated.

Palmer and Price were furious at what they considered to be underhand tactics by their opponents and as the four players came off court, Australia's head coach Roger Flynn tried to calm down his men.

"We expected more sportsmanship from them," said Palmer, who also lost to Nicol in the last four of the individual event.

"Beachill had a good match and was by far the best player. Nicol was average really."

After their 13-15 15-9 15-9 triumph, Beachill retorted: "Their behaviour shows other people not being able to lose professionally.

"It feels great knowing I will leave here with a medal, but we both want gold and that's what we are aiming for."

Nicol added: "It's fantastic to be guaranteed another silver, but it's the wrong colour because I want gold."

Boswell and Ricketts deposed defending champions Mark Chaloner and Paul Johnson of England by prevailing in the longest match of the tournament so far, a 119-minute epic, 15-8 13-15 15-12.

"They were flying the flag for Australia, which would have made them even more determined to beat us," said 31-year-old Chaloner, from Hertford. "I'm not happy with bronze but it's better than nothing."

Cassie Jackman and Tania Bailey will also collect a gold or silver medal from the women's doubles after beating England team-mates Linda Charman and Fiona Geaves today to reach the final.

It was a dramatic encounter won 15-3 16-17 17-15 by the third seeds, with the vanquished pair at least having the consolation of a bronze medal.

"That was one of the edgiest matches I've ever played," said 29-year-old Jackman, from Norfolk, defending the title she won with Sue Wright four years ago. "But as long as we won I wasn't too bothered how we did it."

Bailey, 22, from Lincolnshire, added: "We played really well in the first game but then for some reason we sat back and let them dictate the second. Our minds just seemed to stop.

"It feels great to be through to the final and it's fantastic to have at least a silver, but we really want the gold."

To capture the most coveted prize, the English duo must beat Carol Owens and Leilani Rorani of New Zealand, who knocked out the top-seeded Grinham sisters of Australia.

Geaves also had the misfortune of losing in the mixed doubles semi-finals, and having to settle for another bronze, with Chris Walker to Beng Hee Ong and Nicol David.

In a match which did not finish until 11.35pm and went to a sudden-death point, the English pair succumbed to a 15-14 12-15 15-14 defeat.

The Malaysians will meet Rorani and Glen Wilson of New Zealand in the final.
