Syria's Hend Zaza is already making headlines at Tokyo 2020. She's just 12 years old and is competing in the women's table tennis singles.

Zaza is facing Austria's Liu Jia who has won the first two matches and leads the third game 6-3.

Marcus Ellis and Lauren Smith are in action for Great Britain in the mixed doubles.

It's straightforward enough - all matches are best of three games, with the first pair to 21 points winning the game.

The top two pairs in each group go through after they have all played one another, with Ellis and Smith currently facing off against Thom Gicquel and Delphine Delrue of France.

Ellis and Smith lead 12-9 in the first game.

We haven't seen Helen back in the boat for five years. We all have - and continue to have - high hopes but... we also haven't seen the rest of the world for almost two years.

So, Helen and Polly came back to do the Europeans and they won it, which was impressive.

The big risks, the leading nations while Helen has been away have been the USA, Canada, New Zealand and Australia - they were all to come back in and what they have shown here at the global level is just how good they are.

They have a fight on their hands but this is the Olympics, they won't give the title up easily.

Back to the rowing. What's the verdict on Helen Glover's return to Olympic action? Dame Katherine Grainger has been having her say.

If you can't watch the action on the television then BBC Radio 5 Live has you covered.

Chris Latchem is on air now before Mark Chapman and Rachel Burden take over at 06:00 BST for 5 Live Olympic Breakfast.

They're in game one in the mixed doubles match between Marcus Ellis/Lauren Smith and Thom Gicquel/Delphine Delrue.

Two of Britain's three Olympic badminton medals have come in mixed doubles, and Team GB's hopes in 2021 rest with Marcus Ellis and Lauren Smith.

Ellis, 31, and Smith, 29, are a couple off-court as well as on it - but their personal relationship began after their professional one.

They teamed up to represent England at the 2018 Commonwealth Games, and decided to carry on the partnership after winning a silver medal.

On-court success then developed into off-court romance for the couple who had known each other from a distance since they were teenagers.

Their match against French pair Thom Gicquel and Delphine Delrue is in its early stages.

Not to be for Seonaid McIntosh.

She's finished 12th in the qualifying round, four places off the cut off mark.

Helen Glover and Polly Swann finished in a time of 7:23.98 - a good two seconds behind heat winners Australia. GB qualify for the semi-finals.

This is a big statement from Australia.

It's not great for Great Britain but they will have learned more than anyone else.

You learn a lot from a defeat.

Great Britain could secure their first medal of the Games today, with Seonaid McIntosh competing in the women's 10m air rifle.

Qualifying is ongoing, with the top eight going through to the final, which gets going at 02:45 BST.

It's into the final round, with McIntosh moving herself up into the coveted eighth position.

Glover and Swann finish third in the heat behind Russia and Australia.

GB drop to third at the 1,500m mark. Russia move up to second. Australia still lead.

Nice and steady from Glover and Swann as they reach the halfway point in second. Australia still lead.

Glover and Swann pass through the 500m mark in second place. It's all going to plan.

This is the biggest race of Helen Glover's life in my opinion. The opening heat against the Aussies??? is really going to set the tone.

And Helen Glover and Polly Swann are off. They look nice and relaxed through 250m.

Helen Glover has come up with a novel way to include her young children in her training schedule.

"If it's weights and I am on my own, I can incorporate the kids into the session - I can lift, have a little dance to Paddington Bear, lift again," she says.

Genius.

All races take place over a distance of 2,000m. There are three heats - with the top three into the semi-finals. The rest go into the repechage.

Heat one has just finished with Canada, Romania and Italy advancing.

Whatever happens in this race, it's a phenomenal feat that Helen Glover has been able to get to the Games.
