The Australian superstar is unbeaten in 20 starts in her homeland and is expected to stay on for this third British leg of the Global Sprint Challenge after running first at Royal Ascot.
The Australian team for the July 14 showpiece also includes the Group One winners Foxwedge and Ortensia.
Krypton Factor has proved to be a star for his Bahrain-based owner/trainer Fawzi Nass in Dubai this year, winning the Group One Dubai Golden Shaheen at Meydan.
Nass’ racing manager Oliver St Lawrence said: “Krypton Factor runs in Singapore on May 20 (in the KrisFlyer International) and he should land in England on May 24 with the intention of going on to the Diamond Jubilee Stakes at Royal Ascot and the July Cup at Newmarket.
“He has been very well since his victory in Dubai. We eased off a bit but he wasn’t on the go from the end of Meydan last year to the start of Meydan this year, so he has hardly had a strenuous time.
The last French winner of the July Cup was Marchand D’Or in 2008, and his trainer Freddie Head has two possibles in Moonlight Cloud and Zantenda.
The international entries for the July Cup also include Hong Kong’s Joy And Fun, trained by Derek Cruz, winner of the Group One Chairman’s Sprint Prize at Sha Tin in February.
Several Group One winners are among 31 entries for the betfred.com Temple Stakes at Haydock on May 26.
The likes of 2010 Nunthorpe winner Sole Power, Prix de l’Abbaye scorer Tangerine Trees and King’s Stand hero Prohibit have all been given the option.
Bated Breath, Hoof It, the in-form Mayson and the three-year-olds Best Terms, Burwaaz and Bapak Chinta are others in the mix.
Eddie Lynam is praying it stops raining in time for Sole Power to run.
He said: “Sole Power will run in the Temple Stakes depending on the weather in the next couple of weeks.
“The horse is in great form and we are preparing him for Haydock Park. If the ground is fast, we will be there.
“He did us proud out in Dubai and we were very happy with him. He ran very well last season too and has been second and third in two Group Ones since his victory in the Temple Stakes last year. “The five furlongs at Haydock Park suits him and as long as we don’t get the Irish weather over there he should be fine.
“His programme for this season is pretty simple with the three Group Ones in Europe – the King’s Stand Stakes, Nunthorpe Stakes and Prix de l’Abbaye – so we would like to have a crack at them.”
