"It will be great for me. I know the field will be really strong and that kind of company will only push me to do better and run faster," said Williams.

"I'm feeling really good on track at the moment. I want to keep on racing as much as I can to ensure that I keep on improving and finish 2011 on a high.

"Going into the European Under-23 Championships in Tallinn, I didn't think I'd been performing to my potential, so after racing well there it's given me the confidence boost I needed to compete in a Diamond League meet."

Williams, from Welwyn Garden City in Hertfordshire, is also the world junior champion at 100m, and captured her first senior title in the 60m at the UK Indoor Trials and Championships in February.

The following month, she was just a hundredth of a second away from from a bronze medal at the European Indoor Championships in her first senior international event.

But the teenager and her coach, Mike McFarlane, have decided she will not compete at the World Championships in Daegu, South Korea, in August.
