Lance Armstrong is set to meet French police after a probe was launched into doping allegations against the six-times Tour de France winner.

On Thursday, a French judge confirmed an investigation had been ordered after the publication of a book containing accusations of doping.
"I will make myself available anytime and anywhere to meet with the investigators," said Armstrong.
"I do not use - and have never used - performance-enhancing drugs."
Last July, a Paris appeals court turned down Armstrong's request that the book, entitled "LA Confidential: The Secrets of Lance Armstrong", should include his denial of the allegations.
Armstrong, 33, added: "Let me make one thing emphatically clear: I believe in clean and fair competition.
"I am disappointed in the judge's decision to open this investigation without having talked to me first.
"I am confident my name will be cleared and I look forward to racing in France for years to come."
Armstrong has still to decided whether to ride in this year's Tour but said he would compete in March's Paris-Nice race.
