GB athletes will know the words to the national anthem before the London Games, UK Athletics head coach Charles van Commenee says.

The Dutchman believes the step is necessary to head off potential criticism over "plastic Brits" - athletes who have switched allegiance to represent Team GB at the Olympics.

Van Commenee said: "They know the words, or they will.

"If they don't somebody will make an issue of it."

The 53-year-old added: "(Whether it should matter), that's a different question.

"I'm not going to rehearse everybody because we have 90 athletes, but people that matter... let's say the relevant ones, the ones on your radar (will rehearse the anthem)."

Van Commenee's choice of United States-born Tiffany Porter as team captain for the World Indoor Championships in March sparked the row after she declined to sing God Save the Queen at a news conference ahead of that meeting.

Porter, who qualifies for Britain through her London-born mother and has held a British passport since birth, said she knew the words but questioned her singing ability.
