Eddie Lynam secured a remarkable sprint double at Royal Ascot after Slade Power stylishly claimed the Diamond Jubilee Stakes.
The Irish handler hit the target with Sole Power for a second consecutive season in the King's Stand Stakes on Tuesday and added a second Group One of the week courtesy of his talented stablemate.
Slade Power won as the 7-2 favourite under Wayne Lordan, with fellow Irish challenger Due Diligence second. Aljamaaheer was an honourable third for trainer Roger Varian and jockey Paul Hanagan.
Lordan said: "He travelled real well. I got there a little bit soon and he rolled around with me, but I had plenty left and I'm delighted.
"From early in his career he gets a little bit warm before a race. If he wasn't I'd be worried."
The 14-runner field split into two groups, but it soon became evident that the quintet on the near side were always chasing the game. Due Diligence's jockey, Ryan Moore, was aware of this and nudged towards the middle of the track with three furlongs to run.
The War Front colt was snatched up by the winner very late, but it made little difference to the outcome, even though the stewards held a brief inquiry.
Slade Power was always handy towards the far side, where Astaire made the running before the final furlong. Lynam's five-year-old entire had already taken the lead by then, and was kept honestly up to his work to score by a length-and-a-half. Aljamaaheer was another head away.
The victorious trainer was winning at Royal Ascot for a third time from just four runners this week after Anthem Alexander hit the mark in the Queen Mary Stakes on Wednesday. He said: "I just had the three best horses in their races."
Lynam's sprint kings, both owned by Sabina Power, will now run against each other in the July Cup at Newmarket next month.
Due Diligence could also renew the rivalry in that event. His trainer Aidan O'Brien said: "It was his first time with the older sprinters and really we couldn't be happier. We would have preferred the field to have stayed together. He was a little bit lonely out there and Ryan said he was wanting to drift towards them, but we're delighted."
An early double for Moore and Sir Michael Stoute was enough to seal the Qipco-sponsored top Royal Ascot jockey and trainer titles.
Moore steered home Arab Spring in the Duke of Edinburgh Stakes and then the impressive Telescope in the Hardwicke Stakes for his boss to add to the three victories he took earlier in the week.
Moore ensured he claimed the title for the fourth time in five years with a sixth win when the Willie Mullins-trained Pique Sous rounded off things in style in the Queen Alexandra Stakes.
William Buick was his nearest pursuer on three triumphs.
Stoute, who was already the most successful current Royal Ascot trainer beforehand, now has 72 wins in total after four during the meeting.
The Newmarket operator last received the top trainer prize back in 2006.
Moore, who picked up both prizes, said: "It's nice to win the last, but it would have been nice to win the Golden Jubilee as well.
"The only disappointment of the week was Dank, and it was a shame I couldn't get a winner for the Queen.
"It's gone really well in the main and I'm delighted. It's been a lovely week."
