It all went wrong on the start line for Team GB's John Gimson and Anna Burnet in the mixed multi-hull medal race.

They were judged to have been over the line ahead of time and, as a result, had to withdraw from the double-points race.

That means they take a maximum 22 points and slip from third to fourth, behind New Zealand. The Kiwis came eighth in the medal race but that was enough for them to get on the podium.

France won the race but it is Italy who take the gold medal with Argentina claiming the silver.

Job done for Katarina Johnson-Thompson in the high jump.

She can't quite clear 1.95m but 1.92 is her best jump for five years.

Crucially, though, Olympic champion Nafi Thiam is also unable to go over at 1.95m - and that is more of a surprise.

All of that means that Johnson-Thompson leads the heptathlon on 2197 points after two disciplines. Thiam of Belgium is second on 2173 and USA's Anna Hall is third on 2164.

I just know how devastated Jade will be. Hopefully Miljana Reljikj gets through to the final so it gives Jade a chance in the bronze-medal match in the repechage.

I am gutted. She deserves it and is the greatest. I feel like crying.

A historic third taekwondo gold was not to be for Great Britain's Jade Jones - the 2012 and 2016 Olympic champion

The Welsh fighter was beaten in her opening bout of the women's -57kg competition in Paris by Miljana Reljikj of North Macedonia.

Jones hit back after losing the first round to force a third round decider, but after finishing 1-1 the referee handed the decision to her opponent.

KJT triumphantly thumps the mat!

She holds her nerve to clear 1.92m and the high jump contest is now down to two.

World champion Johnson-Thompson dukes it out with Olympic champion Nafi Thiam.

All eyes on the high jump now. Everyone inside the Stade de France is engrossed.

That's a big clearance for Katarina Johnson-Thompson - and she enjoyed it!

After two failures, the world champion clears 1.92m at the third and final attempt.

On she goes and, with USA's Anna Hall unable to clear at that height, it is just the Brit and defending Olympic champion Nafi Thiam left in the high jump.

To win over and over again is so hard in our sport. Anything can happen and we've just seen it then. On paper this wasn't meant to happen.

There are so many variables. I just hope she can still go far in the competition.

Disastrous start for John Gimson and Anna Burnet at Marseille Marina in the mixed multi-hull medal race.

They're judged to have been over the line when the starting horn sounded so, while their competitors continue, they have had to pull out of the double-points race.

Their best hope of a medal is for this race to be abandoned because of the wind conditions. Were that to happen, they would be able to re-enter.

See what happens now on BBC One.

KJT roars in relief after clearing 1.89m at the second attempt.

The first real bit of emotion we've seen from her today.

Also spotted Jazmin Sawyers - working here as an television analyst for BBC Sport - throwing her arms in the air.

The Brits inside the Stade de France are happy.

So far, so good for Great Britain's Katarina Johnson-Thompson in the heptathlon.

She is still going well in the high jump and has just cleared a season's best 1.89m at the second attempt .

Fellow Brit Jade O'Dowda registered 1.80m after three failed attempts at 1.83m.

Nafi Thiam went over first time at 1.89. No surprise given she holds the world heptathlon best at this event, a mere 2.02m.

Like KJT, USA's Anna Hall cleared it at the second attempt.

Heartbreak for Great Britain's Jade Jones as she loses in the first round for the second Olympics in a row.

North Macedonian Miljana Reljikj produces a brilliant display to put an end to Jones' bid for a third gold medal.

The deciding round was level at 1-1 and more registered hits from Reljikj gave her the win.

Jones may still be given a chance at the bronze medal through the repechage.

Jade Jones wins the round by the skin of her teeth! One point was the difference as the Brit takes it 5-4.

We're now going into a decider to see who will progress to the quarter-finals.

Come on, Jade!

Great Britain's first shot at a medal today comes down at Marseille Marina as sailors John Gimson and Anna Burnet go in the mixed multi-hull medal race.

They're third going into it so a medal is there to be won.

Gold looks to be Italy's to lose but they are right there with Argentina in the hunt for silver.

Great Britain's Jade Jones hasn't produced the start she wanted as a late strike from North Macedonia's Miljana Reljikj takes the first round 7-6.

Jones was piling on the pressure but failed to score points and Reljikj was able to capitalise.

A must-win round now.

I am excited to see my best friend go out there again. Hopefully Jade Jones creates history. The head-hunter is back!

She is a superwomen. One of the best ever in her weight class and in taekwondo. If she gets to the final again, she will be the greatest.
