LONDON — London Olympic organizers say a record 5,000 doping tests will be carried out at the 2012 Games.

The local organizing committee has signed a memorandum of understanding with Britain's anti-doping body and will implement the testing program under the authority of the International Olympic Committee.

London 2012 director of sport Debbie Jevans says the size of the testing program will give a "strong message that drug cheats are not welcome at the London Games."

UK Anti-Doping will train anti-doping officials and assist them during the event to carry out a 10 percent increase on the 4,500 tests conducted at the 2008 Beijing Olympics.
