UK Athletics head coach Charles van Commenee has revealed that all the athletes from Team GB have been informed of the importance of learning the national anthem ahead of the Olympics.
The issue of athletes not knowing the words of the anthem came to light earlier this year when Team GB captain Tiffany Porter refused to sing at the World Indoor Championship, despite claiming that she knew the words.
"They will know the words," ESPN quotes Van Commenee as saying. "The reason I'm so sure is because I asked them. 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 the radar, will know.
"It matters because if they don't [know the words], somebody will make an issue of it. That's why."
Meanwhile, British sprinter Dwain Chambers could miss out on a spot in the Olympic team after failing to claim a time worthy of qualification to the Games during a race in Paris.
