The 80 torchbearers include classical violinist Vanessa Mae, England cricketer Kevin Pietersen television presenter Konnie Huq, retired swimmer Duncan Goodhew and badminton player Gail Emms. They will join Dame Kelly Holmes and Sir Trevor McDonald, whose involvement was revealed last month. The relay will start at Wembley Arena Square, pass the site of the 2012 Games and end in a "grand finale" beside the O2 featuring performances by the Sugababes and a gymnastics display. Eighty people will carry the torch and organisers are expecting large crowds to follow it. Other celebrations include a dragon procession in Chinatown and music and dance in Trafalgar Square.
