Robert Cowell's unbeaten Royal Ascot winner Prince Of Lir is one of two British challengers among six runners in the Prix Robert Papin at Maisons-Laffitte on Sunday.

He is joined on the journey over by Clive Cox's impressive maiden winner Tis Marvellous.

Prince Of Lir won the Brian Yeardley Trophy on his debut at Beverley and followed up in the Norfolk Stakes last month, with Cowell feeling he has progressed again.

"He's been absolutely fine since Ascot and is ready to go," he said.

"Since Ascot he's been really fresh and well, he's in good order so it's all systems go.

"Obviously Clive Cox's horse looked useful when he won his maiden, but we're in the position now where there is only one way to go - people have to come and take us on now.

"We've proved we're fairly useful ourselves, now it's up to the others to prove it.

"I think he'll stay six when he has to, but this is only 100 metres further than Ascot and, if anything, he was the one finishing strongest there.

"What I really like about him is that in both his races he has just kept on finding, and that's a great trait to have."

Cox made the entry for Tis Marvellous before he had even won a race, but he subsequently scored by eight lengths in a six-furlong event at Windsor earlier this month.

"We had to enter him for this before he'd won his maiden at Windsor so I'm pleased we had the foresight to do that," he said.

"Obviously he'd shown plenty on his debut and Newbury and progressed nicely forward from that.

"He fairly hacked up at Windsor and looks above average. This is a big step up in class, but we are confident he is progressing.

"We've won this race before with Reckless Abandon and while this is a drop back in trip slightly, he's all speed.

"On his dam side he is related to a Queen Mary winner and with the pace he showed at Windsor, I'm not bothered about five and a half furlongs."

Mario Hofer's Hargeisa is unbeaten in two but at a lower level than Prince Of Lir, while the Al Shaqab-owned Al Johrah was a clear second-best behind Lady Aurelia in the Queen Mary at Ascot last time.
