Phillips Idowu has revealed that he is in London preparing for the triple jump despite receiving criticism from Team GB's athletics coach Charles van Commenne.

The 33-year-old has been recovering from a trapped nerve ahead of the Olympics but he has rejected claims that he his coach did not know of his whereabouts.

"I'm in London where I have been for the last few weeks, finalising my prep and receiving therapy," Idowu posted on Twitter. "My coach knew about this and it has not been a secret."

"I've only heard about the hysteria about my whereabouts today as I've been on a media lockdown, I'm into the village on Sunday as was planned months ago."

The triple jump competition starts on Tuesday.
