The cross country mountain biking has just got under way with GB's Thomas Pidcock going for a medal.

He's handily placed in fifth after the first lap.

It must be very daunting and Matty said himself it was nerve-racking being asked to step up into the role. Particularly as at Rio, the pairing of Tom and partner Daniel Goodfellow were bronze medallists.

But he also said that it was a great opportunity and that his diving improved immensely when he made the move down to training in London alongside Tom.

Oooh. Big, big dive from the Chinese pair and a massive 54 points to open.

It puts them narrowly ahead of Great Britain's Tom Daley and Matty Lee, who are tied for second with the Russian team.

You can just hear Tom counting them in on the platform.

That was a beautiful entry, wonderfully in time.

Yes boys - exactly what we wanted, Steady, calm.

This pair - their success speaks for itself.

We're under way at the Tokyo Aquatics Centre. And here are our Great British pair...

That looked good! What do the judges think? An inward 1.5 somersault that puts 52.80 on the board and fires them to top spot after five countries have dived in the opening round.

A cracking start.

Tom Daley is Britain's most decorated diver, but he possesses a level of fame that far transcends his discipline.

He has become one of sport's highest-profile gay athletes, a role model for others in the LGBTQ+ community.

He has suffered several media run-ins during the course of a life lived under the spotlight. Now aged 27, Daley still wants an Olympic gold medal.

And Tokyo - his fourth Olympics - arguably represents his last realistic chance to claim it.

Their chances are really good. No-one's competed and they're all in the same boat.

I hope Matty (Lee) doesn't put too much pressure on himself because I know what it means to him to be an Olympian.

Plenty of people tried their hands at something new as a way to keep busy during lockdown last year, for Tom Daley it was taking up crochet - now can he and partner Matty Lee knit together a medal-worthy performance in Tokyo?

Here's something to make you feel old - it's 13 years since Tom Daley made his Olympic debut, almost half his lifetime ago...

Since then, the 27-year-old has collected bronze medals at London and Rio, been crowned world champion numerous times, got married and become a father.

Now in his fourth Olympics, Daley teams up with Matty Lee to go for a medal in the men's 10m synchronised platform event.

Britain's Adam Burgess is safely into the men's canoe slalom final with a controlled run in the semi-final.

Despite a penalty at the 18th of the 25th gates, he is eighth fastest into the 10-paddler final at 07:45 BST.

Team GB's youngest sailor Emma Wilson is seeking her first senior medal in Tokyo - and couldn't have made much of a better start.

Wilson has won one of Monday's three races, as well as finishing fourth and second in the other two, which puts the 22-year-old in the silver medal position overall after six events.

She's level on points with France's Charline Picon, who sits first.

Still a long way to go, though - six more races, followed by the medal race.

Great Britain's Lauren Williams reached the quarter-finals in the women's -67kg category a little earlier. That will take place around 07:30 BST. Here's how she got there...

Great Britain's men got the job done against Canada a short while ago, earning a 3-1 win.

Canada pulled a goal back to trail 2-1 with minutes remaining and looked set to make it a nervy finish until Liam Ansell tapped in his second of the match.

It's now two wins from two for Great Britain and they sit second in their six-team group. Four will qualify for the quarter-finals.
