Another heavy crash takes out two riders - GB's Hamish Turnbull and Germany's Luca Spiegel.

Spiegel fell first and clipped Turnbull's rear wheel, sending him spinning towards the barrier before crashing to the floor.

Both riders get to their feet, albeit a little gingerly. Spiegel gives a wave to the crowd to show he is okay.

Australia's Matthew Richardson, Harrie Lavreysen of the Netherlands and Japan's Kaiya Ota qualify for the final, which will feature GB's Jack Carlin, at 12:32 BST.

Kerenza Bryson is a qualified scuba diver but the swimming is her weakest event.

Unfortunately that showed. She trailed the field by a way and drops to seventh overall before the concluding laser run.

This consists of a 3,000m run, split into five 600m laps, and four visits to the shooting range.

The athletes start with time handicaps – one second for every point they’re behind the leader - which means Bryson has a lot of ground to make up.

I'd suggest that her medal chances are slim.

Right then, this is it for Kerenza Bryson as she goes for the final time in the laser run.

She needs to make up 30 seconds to land herself a spot on the podium.

Is it possible? We'll find out shortly.

And in fact, that's your lot for the snatch.

China's Liwenwen is unsurprisingly first after that massive 136, followed by Park Hye-Jeong with 131.

Britain's Emily Campbell is in third with 126 - a bit of a gap on fourth-placed Lisseth Ayovi on 123.

Campbell is in a good position at the halfway stage.

Jack Carlin is looking very, very good. A reminder he broke his ankle in APRIL!

He cruised to that win and is through to the medal race.

That was perfect for Carlin. He didn't panic at all. That was beautifully ridden by Carlin.

That was mightily impressive from Jack Carlin, who breezes through to the final of the men's keirin.

Next up is Hamish Turnbull.

Li Wenwen has just lifted 136kg like she's lifting a stack of carrier bags out of the cupboard.

Absolutely effortless.

There have been plenty of famous faces in the crowd throughout this Olympics and the latest to join the club is former Netherlands and Manchester United goalkeeper Edwin van der Sar.

He is in the crowd at the Velodrome in what has already been a busy morning of cycling, including a strong Dutch presence across the cycling events.

Back to the velodrome for the men's keirin semi-finals, with GB's Jack Carlin in heat one and Hamish Turnbull in heat two.

The first three riders from each of the two heats qualify for the final.

Just moments ago Sophie Capewell, who was beaten in the women's sprint quarter-finals on Saturday, won her fifth-eighth race to take fifth place.

It's 267 points for GB's Kerenza Bryson to add to her overall, taking her to 783.

France's Elodie Clouvel leads the way on 844, Hungarian Michelle Gulyas is 13 points adrift in second while South Korea's Seungmin Seong is third on 813.

Bryson needs a huge turnaround in the laser run if she's to win a medal.

The more on the bar, the bigger the smile. Emily does it again! Three from three in the snatch, 119, 123 and 126.

MASSIVE!

Emily Campbell roars to the roof as she gets the 126kg weight up and over her head.

Three attempts, three passes - but Korea's Park Hye-jeong has just cleared 127kg, and China's Li Wenwen has yet to go...

Emily Campbell is in very good form here and she has one more snatch attempt.

She will be trying to match her personal best.

Final attempt for Emily Campbell in the snatch.

There's a bit of back and forth as the weight keeps going up and up, trying to match Park Hye-jeong, and the Brit has decided to have a crack at 126kg.

123kg for Emily Campbell up next...

...and a giant smile on her face as she hoicks it above her head with an ease I can only dream of.

Park Hye-jeong had just lifted the same weight - and we've yet to see China's Li Wenwen, who is starting at such a heavier weight than anyone else.

A quick update on the medal table as Great Britain find themselves in sixth on 14 gold, 22 silver and 27 bronze.

The total so far is 63 medals but there's still a number up for grabs today.

Will GB jump ahead of France in fifth?

Thailand's Chaidee Duangaksorn has just failed at her first attempt at 120kg.

That was going to be Emily Campbell's next weight, but she's upped the stakes and will attempt 123kg next.

It's the leading six women all against each other in this 200m freestyle swim.

The pressure is on for all of them, including GB's Kerenza Bryson.

A very confident start from Emily Campbell and a tremendous reception from the Parisian arena.
