Adrian Moorhouse
1988 Olympic 100m breaststroke champion on BBC TV
"It is the IOC's party and they can decide who comes to it and who doesn't. But they just wimped out by letting Efimova compete. If you have a ban you shouldn't be allowed to compete in the Olympics ever. It was nice to see Lilly King giving her the daggers."

The athletes are out - Yulia Efimova gets booed in by some in the stands...
Women's 100m breaststroke
From Anna Thompson in Rio:
"There are many who are unhappy Yulia Efimova is competing in Rio and she was booed in her semi final. She qualified second fastest in the 100m breaststroke and we're minutes away from what could be a very controversial medal."
Sun has got his hat off!

Women's 100m breaststroke
Yulia Efimova will be an 'interesting' champion if she wins in the next race - she will go for gold just weeks after being cleared to compete at all.
The 24-year-old was banned between 2013 and 2015 for taking steroids, and tested positive for meldonium in March of this year. But here she is...
Men's 200m butterfly
Remember Chad le Clos's dad, Bert, from London 2012?
Of course you do! The big man was an even bigger hit after his emotional interview with Clare Balding moments after Le Clos pipped Michael Phelps to 200m fly gold.
Well, since then Bert has been diagnosed with prostate cancer, and wife Geraldine has had a double mastectomy. What a tough year for the family.
Tonight sees Chad le Clos and Phelps go head to head once more in the same event. That semi-final is at 03:19 BST. Do not miss it.
Britain's Paul Drinkhall now trails by just one game against veteran Vladimir Samsonov as he seeks a historic quarter-final spot.
The man from Middlesbrough saved seven match points in the third game, remember.
It's a best-of-seven shootout.
