There's a new roar from the crowd at this year's Royal Ascot - the Meghan and Harry Roar.

But as Frankie Dettori entered the parade ring the volume of the classic Dettori Roar still beat the new kid on the block.

That was a classy display from Calyx, a son of the 2014 Irish 2000 Guineas winner Kingman, trained by John Gosden.

It was a 57th win at Royal Ascot for Frankie Dettori, the meeting's leading jockey among those currently riding, who stole a march on the nearside.

Bookmakers reacted by cutting Calyx's odds for the 2000 Guineas next year to about 8-1, from 16s.

I have just caught up with Gaie Johnson-Houghton, who bred Queen Anne Stakes winner Accidental Agent which was trained by her daughter Eve.

She told me she tried to sell him, explaining: "I breed a few as a hobby, and nobody bid enough for him when I tried to sell him, so we bought him back for a reduced price."

Mrs Johnson-Houghton has been involved in training racehorses throughout her life, alongside her husband who used to own Eve Johnson-Houghton's Blewbury yard.

"It's a very long time since we had a winner and it certainly does not feel much worse", she told me on BBC Radio Berkshire.

Next up is the Coventry Stakes (15:05) – a leading contest for two-year-olds, the youngest group of racehorses.

Last year’s victor Rajasinghe may not have won since but 2009 winner Canford Cliffs went on to take the Irish 2000 Guineas while Dawn Approach (2012) later landed the English version.

This time Calyx, a son of 2014 Irish 2000 Guineas winner Kingman, represents the powerful combination of jockey Frankie Dettori and trainer John Gosden.

During Ascot, we will be taking a look at some of the best moments of modern times.

Among the very best was Frankel's win in the Queen Anne Stakes on the first day of Royal Ascot 2012.

He won by an extraordinary 11 lengths and was retired to stud in October of that year after a final victory at Ascot left him with an unbeaten 14-race winning record.

"Frankel doing anything at Royal Ascot was memorable", says BBC horse racing correspondent Cornelius Lysaght. "All of his victories were special occasions."

"He has an amazing fanbase, part of it was because he was trained by Henry Cecil, the most successful trainer of modern times, and he was also UK-based."

A massive turn-up in the opener as 33-1 shot Accidental Agent gives trainer Eve Johnson-Houghton and jockey Charlie Bishop their first victory at Royal Ascot, in the Queen Anne Stakes.

Johnson-Houghton had spoken to the BBC about her hopes before the meeting, but was left in tears by this landmark success.

"I thought I was tilting at windmills," said the trainer, whose mother bred the winning horse.

The family took the horse back when it went unsold at auction for £8,000. Prize money for the Queen Anne winner...£367,000.

We kick off the racing action with the Queen Anne Stakes (14:30) which brings back memories of the legendary Frankel’s victory six years ago.

Frankel won by 11 lengths – that’s around 88 feet or 27 metres.

Don’t expect such a big margin today, but there’s plenty of intrigue - Aidan O’Brien will hope Rhododendron flowers, while Recoletos is a strong French challenger.

Get set for some fast times...

Just before the Royal Procession, it was announced the Queen had another grandchild.

Zara and Mike Tindall have welcomed a baby girl, Buckingham Palace announced.

The Queen's granddaughter gave birth to her second child, weighing 9lb 3oz,at Stroud Maternity Unit in Gloucestershire on Monday.

The new baby, who is 19th in line to the throne and the Queen and the Duke of Edinburgh's seventh great-grandchild, is a younger sister for four-year-old Mia Tindall.

For those intrigued by what the Duchess of Sussex would be wearing, here it is.

She is stepping out for her debut at Royal Ascot, wearing Givenchy, who made her wedding dress.

On the glorious Oxfordshire downs lies a racing family dynasty.

Eve Johnson-Houghton's family have owned their Blewbury-based stables since the war, when her grandmother trained horses. She was a pioneer for the sport.

"Women weren’t allowed to hold the licence, so a series of men held the licence while she trained," she said.

After taking over from her father, she has become a pioneer herself as a leading female trainer in a sport traditionally dominated by men.

"A lot of men are lucky that their wife is involved in the business. I think that’s why it’s harder for women, she said.

"I think there should be more of us because we are definitely as good of them."

One of her best chances for victory is first up this morning in the Queen Anne Stakes with Accidental Agent, as well as Goring in the Royal Hunt Cup.

Breaking news from the world of hats.

The Queen is wearing a yellow hat, which actually was quite high in the betting odds.

A bright hat for everyone to take notice of. Also perfect if Her Majesty is cycling home.

The racing plays second fiddle around now to the highest profile bet of the day... will it be brown, red or blue for the Queen?

Well this bookie seems to think blue - who knows? Not us that's for sure.

Don't worry, the waiting is nearly over.

We are moments away from seeing the Queen and accompanying guests, but who exactly will be towing them, in their carriages, from the Golden Gate at Ascot to the Royal Enclosure?

The rather striking Windsor grey and Cleveland Bay horses is who.

The horses train as carriage horses, beginning at four years old and working for approximately 15 years.

Windsor greys are not a breed, but horses specifically selected for ceremonial duties because of their appearance and temperament.

Cleveland Bays, meanwhile, are a breed of horses originiating in England in the 17th century. They have frequently been close to extinction but have been saved through passionate breeders and advocates, including the Queen.

With 10 minutes left until the Queen arrives to kick off Royal Ascot 2018, it's time to take your seats... We think there are still a few spare.

We think everyone else is still working their way through those 7,000 rump steaks.

Irish trainer Aiden O'Brien is a giant of the flat-racing world, who is attempting to claim the top trainer award for a fourth year on the bounce.

The statistics keep coming. He has 61 Royal Ascot wins to his name (the second highest ever).

Add to that his prolific partnership with jockey Ryan Moore, and you have a continually formidable prospect.

But is this going to be his year?

"He will have a huge number of runners, but if you were to pick out one it would be Order of St George in the Gold Cup - he came second in 2017" says BBC racing correspondent Cornelius Lysaght.

"He’ll have stacks of runners, but there’s nothing especially sexy in 2018."
