Mark Foster

Mark Foster

Mark Foster is arguably the most successful swimmer Britain has ever produced. Six times a World Champion, his bulging trophy cabinet holds 10 European Champion medals and two Commonwealth Champion medals. He has also broken eight world records in his career.

August 2008 saw Mark compete in his fifth Olympic games - recognising this feat, Mark was voted by his team-mates as the Team GB member who would carry the British flag at the Olympic Opening ceremony.

Hayley Holt

Hailing from Auckland, Hayley joins the Strictly roster for the first time this year. She started ballroom and latin dancing at the age of seven, and her accolades include New Zealand Professional Ballroom Champion.

Hayley thinks it's hard to remember that Ballroom and Latin dancing are such a foreign concept for the celebrities: "I try not to hit them with too much information straight away."
