Olympic long jump champion Greg Rutherford has claimed that Brits are being forced to battle a "class system" within UK Athletics.
Rutherford has often been critical of UK Athletics, the sport's governing body in Britain, and he believes that the problems will become clear to the public in the near future after voicing his displeasure with their service once again.
"Things that will come to light we've been dealing with for the last few years," the 28-year-old told BBC Radio 5 live after reaching the long jump final at the World Athletics Championships.
"Things have not been working very well for me. As things come out, we'll see there are different class systems within the system which I don't think works well and, for me, is a massive hindrance.
"It's safe to say there's a bit more to come out in the coming months."
Rutherford will look to add the world title to his Olympic, European and Commonwealth gold medals when he competes in the final on Tuesday.
