England's double gold medal winner Kanukai Jackson can take gymnastics to a new level, according to team manager Michael Weinstock.

The Londoner added individual all-round gold to the one he picked up in the team event on Friday.

And the 24-year-old can pick up a further six medals today when he takes part in the finals of all six apparatus competitions.

Weinstock said: "I thought Kanukai was fantastic in the all-round event and showed confidence and strength that perhaps we haven't seen before in this country.

"He did really well in the European Championships to win a bronze and has showed amazing strength of character."

Beth Tweddle continued England's impressive performances in the gymnastics with a silver medal in the women's individual all-round event later in the evening.

The 17-year-old from Liverpool added to her silver with the women's team, and is highly fancied to take gold in the uneven bars final today.

Tweddle held her nerve to overhaul the more experienced Allana Slater, and also earned praise from Weinstock.

"The reason that Beth came through was heart and guts, she really wanted to do it and that paid off in the end," he said

"It was the same with Nicola Willis on the beam on Saturday. She held her nerve and pulled it out of the bag when it was needed."

Jackson had kick-started another profitable day at Manchester's G-Mex Arena for the English team by finishing ahead of Australia's Philippe Rizzo and Canadian Alexander Jeltkov in a tense finale.

The victory was just reward for Jackson, who missed the 1998 Commonwealth Games with a ruptured cruciate knee ligament and needed an operation in December to have fragments of bone removed from his ankle.

"After injuring my knee, I was worried about whether I'd be able to compete again on all six apparatus in an all-round event," he said.

"But I had a lot of treatment and managed to come through all right, now I don't have any problems."

The turning point in the race for gold came in the penultimate round when leader Jeltkov fell off the pommel horse, immediately losing 0.5 points of his mark.

That mistake let Jackson into the lead for the first time after he turned in a near faultless display on the parallel bars moments later.

He then showed nerves of steel on the high bar to make it another golden day for English gymnastics.

Team-mate Craig Heap finished fifth and admits he will call it a day after competing in the high bar.

"It's looking very likely that I'm going to retire," said the Newcastle-based gymnast.

"I treated yesterday like it was going to be the last time I compete so just wanted to do as well.

"I only fell on the rings, but that was only because I tried a triple back somersault for my dismount.

"I just wanted to give it my best shot and have a good memory if it was going to be my last Games.

"The Olympics were my time and I got a personal best there. All credit to Kadge, it's his time now.

"You spend time getting there, but then you have the downside of coming down.

"I'm just the wrong side of 25 to compete for the number one spot."

Heap, who was born in Burnley, believes Jackson can increase his medal tally yet further today.

"I think he can definitely take a medal on every piece of apparatus and he is probably going to come away with a few more golds as well," said the 29-year-old, who delighted the crowd yesterday with his celebratory antics.

Tweddle rated her silver even higher than when she became the first British female to win a medal at the European Championships, taking bronze on the uneven bars earlier this year.

"This is a higher achievement because I have never had one of these silver medals for myself before," said the 17-year-old.

She was beaten to the gold by Canadian Kate Richardson, whose success came only six months after major back surgery.

"My back was in a brace for six weeks and I could not move," she said.

"It wasn't for another three months before I could start jumping and twisting again. I was not expecting this at all."
