La Defense Arena is being treated to another blast of 'God Save the King', as women's S3 50m backstroke champion Ellie Challis is being presented with her gold medal in Paris.

Everyone wants to have a look at the world champion's new piece of silverware, which was won in commanding style by GB's Challis with a lifetime best of 53.56 seconds.

The standard is so, so high in this final.

A couple of nines for Nathan Macqueen, a couple of 10s for Jodie Grinham - but Iran do even better.

It's all square at 77-77 at the halfway point.

It was bronze for Great Britain's Jonnie Peacock in Tokyo. What will tonight bring?

We'll find out in around 20 minutes.

Jodie Grinham - with her second child due in October - has had to make numerous adjustments to her kit and equipment to work around her growing bump.

It’s not just slightly bigger clothes - but the belt which holds her quiver needed to be made longer too.

She and Nathan Macqueen (and her baby bump) are hoping for a golden evening in Paris.

A perfect start for GB as Nathan Macqueen and Jodie Grinham start with 10s.

Nerve-settlers, if they were needed. The British pair look rock solid.

A total of 39 from their first four arrows, one more than their counterparts from Iran.

The final medals are being decided in the pool and the latest para-swimmer to stand on the top step of the podium is neutral Paralympic athlete Dmitrii Cherniaev.

Russian Cherniaev successfully defends his Tokyo title and finishes 3.96 seconds ahead of Antonios Tsapatakis of Greece, who takes silver, with Italy's Manuel Mateo Bortuzzo taking home bronze.

Jodie Grinham and Nathan Macqueen are just moments away from their final - and a chance to become Paralympic champions for the first time.

We’ve just seen a nail-biting bronze medal match, which India won 156-155 against Italy - equalling the Paralympic record Britain had just equalled themselves.

Here we go then - a chance for gold for Great Britain's Nathan Macqueen and Jodie Grinham.

After winning bronze in the women's individual event, Grinham - who is competing while seven months pregnant - said she didn't think there was a reason why she couldn't be competitive in Paris.

Their opponents in the final are Hadi Nori and Fatemeh Hemmati of Iran.

India have just won the bronze medal, beating Italy in a very high-scoring final.

GB's Stephen McGuire, speaking to Channel 4 after winning gold in the men's BC4 individual final: “I've played this sport for 20 years and I've been in every possible final, apart from the Paralympics, I've never even been to the podium. I was starting to feel this event was getting away from me, two fourths in London, another fourth in Rio, I didn't even make the semis in Tokyo, it just shows why you should never give up.

"I felt really confident in the final. My flatmate is David Smith and he's won three golds, he told me to have no regrets and told me not to settle for silver, just go for it.

"There weren't many nerves, there were more in the semi-final because I've lost the last three. It's a Paralympic final, I may never reach another one, so I told myself to enjoy it."

Alfie Hewett booked his spot in the men's singles quarter-final in a tough third-round match, beating Daisuke Arai 7-5 6-2.

Hewett was tested in the first set by the 16th seed from Japan as his serve, and sometimes his temper, deserted him.

The second set was much more settled as Hewett settled himself to take command of the set.

He joins his doubles partner Gordon Reid in the quarter-finals.
