The 20-year-old, who studies Sports Science at the university, improved her record by one centimetre in going over at 4.72m, and managed 4.80m at the first attempt.

She then cleared 4.87m at the third attempt to win the event and assume the lead in the world rankings. 

Only world record holder Yelena Isinbayeva of Russia has gone higher, with a clearance of 5m. Although Holly was unable to beat that record and clear 5.10m, she was delighted with her performance.

"I just lay still on the mat in astonishment. The crowd was absolutely electric and this was an amazing boost.

"I was lucky to have the chance to attempt a world record but next time I will be more mentally prepared," said Holly, who is also optimistic about competing at the London 2012 Olympic Games.

UK Athletics head coach Charles van Commenee praised Holly and stated that she will continue to improve in the run-up to the Olympics.

He added: "If Holly manages to repeat this in the Olympic arena we will all be partying afterwards. I expect more athletes to make a strong mark in the months to come."
