John Gosden has revealed Frankie Dettori will be aboard both Inspiral and Emily Upjohn in their next outings, with the post-Royal Ascot "sabbatical" between the trainer and jockey appearing to be over.

There had been plenty of speculation over who would take the ride on the two Clarehaven fillies, with the long-time partnership between the duo seemingly strained following several high-profile defeats this season.

One of those came on Emily Upjohn in the Oaks when she lost by the barest of margins having stumbled coming out of the stalls. But Gosden, who trains in partnership with his son Thady, has made a quick U-turn and the 51-year-old Dettori's name will appear against Inspiral’s when the Coronation Stakes winner lines up in the Tattersalls Falmouth Stakes at Newmarket on Friday.

Dettori has partnered the unbeaten daughter of Frankel in four of her five starts and Chris Richardson, managing director of Cheveley Park Stud, was pleased to hear the decorated rider will again be in the saddle.

He said: "Frankie has ridden her four times and knows her better than anybody and we’re obviously pleased that John Gosden has decided to put Frankie on board.

"It was very much an issue between John Gosden and Franke Dettori and we have just been waiting to hear what the decision was. We are pleased that the internal issues at Clarehaven have resolved themselves.

"She gave us a great thrill (at Ascot) and Mrs Thompson has said it was one of the greatest days of her racing life. We are all looking forward to seeing her run at Newmarket."

Dettori partnered Emily Upjohn in a gallop at Newmarket on Tuesday morning when Gosden confirmed the Italian would retain the ride on the filly in the Juddmonte Irish Oaks on Saturday week.

Gosden had said at Sandown on Saturday that he had been impressed by Dettori's attitude since the break and that "he and I will be back together quite sensibly when we've passed through this".

Emily Upjohn had been second-favourite for the King George VI And Queen Elizabeth Stakes at Ascot but the decision has been taken to keep her against her own sex for the time being.

She worked with an older stablemate, pulling nicely clear.

"It was lovely ground and it is in perfect condition for the July meeting. I was very happy with her work and she is pointing towards the Irish Oaks," said John Gosden.

"It is nice to get her on to the grass and have a feel of the track.

"We’ve decided to stay with the three-year-old fillies for the moment. I’ve got a lot of respect for the two Derby winners (Desert Crown and Westover) and the Arc winner (Torquator Tasso) who are all pointing towards Ascot so why not stay with the three-year-old fillies at this stage."

Looking back at her luckless run in the Oaks Gosden said: "The less we say about Epsom the better. The track was no problem at Epsom, she didn’t mind the track at all. You just can’t get left and sweep around the whole field. I don’t want to talk about that any more as it is over and gone.

"Frankie has been up here riding work and he will be hopefully riding her. The plan is for him to ride her in the Irish Oaks that’s why he was up here this morning.

"You know what it is all about. I need a jockey that focuses. It can’t be a part-time job. As it was pointed out at Wimbledon, Rafa Nadal practises the most and the hardest in the mornings. That is what it is all about and that is very clear.

"I said I’m pleased the way Frankie has got on with it and getting rides everywhere else. It is exactly what I wanted to see. He has rather taken a lot of pride in how few mounts he has in a season.

"I’m very clear that working with him in the last seven years we have been very careful how we’ve managed it and the rides. He doesn’t need to be charging off to the small tracks. Those days are over. We did that in the 1990s together but I’m very clear we need to be more focused and a little less part-time, that is all. That is what it is about and nothing else. That is all I’m going to say."

Speaking later on Nick Luck's Daily Podcast, Gosden added: "I don’t want to see him chasing up and down the country, not in the slightest, I just wanted to see more focus because the requirements of race-riding are not something that you can just do half-hearted.

"Being a jockey is demanding, it needs sharpness and focus. He’s never been an easy person to manage – as others have discovered – but we have a good relationship and hopefully we can get right back on track together now.

"I don’t think running around the boxes in top hat and tails before racing at Ascot and trying to tip people through the card for a few pounds on the side, I don’t think that’s a professional approach. Do that when you’re retired, not when you’re race-riding. That kind of thing doesn’t amuse me – we’re meant to be focusing on the horses and on the races.

"Look, he is a great jockey but he can be easily distracted – and that’s what was beginning to frustrate me. I think at a certain stage of your career, you’ve got to be careful – you’ve got to stay on top of the game because there are a lot of young ones out there trying to take your position."
