Team GB up next.

A reminder that Ed Clancy had to pull out of this one and announced his retirement because of a back injury.

They are up against Denmark. This will be tough.

It's a huge time from Italy.

They set a new world record of 3:42.307 buoyed by the might of four-time individual pursuit world champion Filippo Ganna to take victory against New Zealand.

Chapeau Australia.

There hopes of going for gold were pretty much blown the moment Alex Porter crashed after his handlebars fell off in qualifying.

But what about that for a response. They set a new Olympic record as they almost catch Switzerland.

Someone who knows how it feels to smash a world record... Michael Johnson shows his appreciation of Norway's Karsten Warholm's record-breaking run.

And here's the silver medal in the mixed Nacra 17 class.

Double gold for Team GB in the sailing!

Ethan Hayter, Charlie Tanfield, Ethan Vernon and Ollie Wood are aiming for a fourth consecutive team pursuit gold.

They do so of course without Ed Clancy, who has been part of all previous three.

Clancy who is the most successful team pursuiter in Olympic history called time on his career earlier on Tuesday.

Heat one: Canada v Germany

Heat two: Australia v Switzerland

Heat three: Italy v New Zealand

Heat four: Great Britain v Denmark

• GB's women's team pursuit team break the world record (which is later broken again) to reach the final but crash afterwards.
• Norway's Karsten Warholm won men's 400m hurdles gold with a new world record.
• British medal hope - sprinter Adam Gemili - suffered injury heartbreak in the men's 200m and didn't complete the race.

Until Jack Laugher and Chris Mears came along five years ago, British diving had never got a gold medal at the Olympic games.

He delivered that, he also got silver at that games as well and guess what, it is the full set with the bronze medal here.

This was never a sure thing for Jack. He has had to battle all of the way. He has turned up here and done a great job. He should be very proud of that bronze medal.

Well done Jack Laugher!

Ryan: A huge congratulations to Jack Laugher on winning bronze on the 3M springboard diving final. Very hard competition but you've made all of GB proud. Well done mate.

If you missed any of the women's cycling team pursuit earlier, you can watch it back on BBC One now.

Xie Siyi put that out of reach. Wang Zongyuan, the younger countryman, responded with rapturous applause because he knew he was looking at the Olympic champion.

Ryan Owens and Jack Carlin hurtle around a smidgen under the Dutch time...

The delivery to Jason Kenny sees that slip off to leave GB with the second fastest time.

There'll be relatively happy with that mind.

Xie Siyi is a master. There is a reason he is a two-time world champion and that he won gold with Wang Zongyuan earlier in week.

GB's James Heatly congratulates Jack Laugher.

China's Xie Siyi is in tears. He was magnificent!

Nothing from France and New Zealand to upset the Dutch and Australian teams.

But what can Great Britain do?

The word on the grapevine is that GB have been going very well in training – and in Jason Kenny they have someone who knows all about peaking for an Olympics.

Kenny is Britain’s most successful Olympian (along with Sir Chris Hoy) with six golds and a silver.

Great Britain's Jack Laugher wins bronze in the men's 3m springboard final.

China's Xie Siyi wins gold and compatriot Wang Zongyuan picks up silver.

Ahhh, that's good from China's Wang Zongyuan. He grabs 102.60 and that will move him up to second, moving GB's Jack Laugher down to third.

Here comes the Olympic champion elect Xie Siyi... He just needs to complete this dive well.

A lot of splash but he has definitely got the bronze medal with that dive.

You would not want to be following Jack Laugher there.
