Polish Formula One driver Robert Kubica sidestepped a claim on Thursday that he owed his life to the miraculous powers of Pope John Paul II.

The 22-year-old comes from Krakow, the late pontiff's home city, and has long raced with John Paul's name on his crash helmet.

Poland's local PAP news agency reported that Kubica's survival after slamming into a wall during this month's Canadian Grand Prix could serve as evidence of a miracle in the Catholic Church's beatification process of John Paul.

The report was based on a Church source.

"I know nothing about this," Kubica told Reuters at the French Grand Prix, after being passed fit to race again on Sunday.

"In Poland there are many things that are reported that are not true.

"I don't know by whom I was saved, I don't know if I was saved by someone. I'm here in one piece so I think that is very positive," he added.

The documentation needed to make the late Pope a saint is prepared by the dioceses of Krakow and Rome and reviewed by the Vatican's Congregation for the Causes of Saints.

The evidence already gathered includes testimony from some 130 people as well as scrutiny of John Paul's life, spoken words and writing.
