Athletics star-turned-amateur ice-skater Colin Jackson has confessed that he and Dancing On Ice Goes Gold partner Frankie Poultney can’t stop giggling during training.

Former Olympic silver medallist Colin is taking part in a special one-off edition of the ITV1 show to mark the beginning of the Games with fellow athletes including javelin thrower Tessa Sanderson and rower Steve Williams.

But the 45-year-old admitted: “Frankie and I get on like a house on fire. I know who’s the boss and it’s definitely not me, that’s for sure. It would be so much better if we spent more time ice skating instead of laughing, we have a proper giggle.”

Colin, who will be skating to September by Earth, Wind And Fire, added: “It’s far more tiring than I ever thought it would be. It’s very exhausting.”

Meanwhile Tessa, 56, said she was having a “heavenly” time.

“It’s really fun, it’s graceful and it’s lovely to see the different age groups that are involved and that’s what I love, it’s a real mix.”

She added: “This is a very nerve-wracking game and my sporting background helps me to be patient. It helps me to understand that it’s not just going to happen after a week. I hope it’ll drag out that competitive element because right now I’m not even thinking about it.”

Dancing On Ice Goes Gold is on ITV1 on Sunday, July 22.
