Great Britain's track and field team will not be allowed to attend the opening ceremony of the 2012 Olympics.
The London Games will open on Friday, July 27, a week before the athletics event begins on August 3.
UK Athletics head coach Charles van Commenee says the Opening Ceremony doesn't fit in the professional preparation for the biggest event of an athlete life.
He says the performance is number one and the athletes can do the closing ceremonies.
The Dutchman believes that if athletes were forced to stand for long periods during the ceremony it may be detrimental to their chances of success.
The head coach further says some of the athletes will still be at training camps at the time of the curtain raiser.
