Dave Brailsford may face further questioning and other witnesses may be called as part of the British Parliamentary investigation into combatting doping in sport after doubts emerged that UK Anti-Doping (UKAD) had obtained Bradley Wiggins' medical records and found the paper trail that would prove that he was given Fluimucil at the end of the 2011 Criterium du Dauphine.
Brailsford stole the show during his questioning at the hearing of the Culture, Media and Sport Committee on Monday by finally revealing that the mysterious Jiffy bag transported by Simon Cope to Team Sky contained Fluimucil, a legal mucolytic that can help break up mucus in the lungs. Brailsford is the only person to so far reveal the name of the contents of the Jiffy bag, claiming that he was told it was Fluimucil by Dr. Freeman, the then Team Sky doctor, who is at the centre of the case.
Brailsford is also under scrutiny after the Daily Mail newspaper claimed that he tried to 'kill' the original story that broke the news of the Jiffy bag.
According to reports in several British newspapers, Wiggins' medical records have not yet been shared with UKAD, who are investigating 'an allegation of wrongdoing in cycling'. However, Brailsford told the parliamentary hearing they had.
The Times newspaper reported that UKAD had been unable to find any written record at British Cycling of what was sent in the package. According to UKAD's official medical guidance, Fluimucil is a prescription-only medication, which means that it should have been recorded if prescribed. The Medicines and Healthcare Regulatory Agency says it has always been prescription-only.
Brailsford was not speaking under oath during the parliamentary hearing, and there is no suggestion he intentionally misled the select committee. There could also confusion about what the term 'medical records' actually means.
Team Sky issued a statement on Tuesday defending Brailsford.
"Dave gave public evidence to the Select Committee yesterday for an hour as part of their inquiry into anti-doping. As we have always said we believe what is most important is for UKAD to establish the truth independently. We are confident that when they report it will be clear that there has been no wrongdoing," the statement reads.
"During the Committee session, Dave acknowledged once again his own mistakes in handling the issue over recent months. We are continuing to co-operate fully with UKAD and we look forward to their report."
However, Damian Collins MP, the chairman of the parliamentary select committee, questioned why Brailsford went to such lengths to try to stop the Daily Mail report if the drug in the mysterious Jiffy bag was a simple mucolytic.
"We will monitor UKAD's report closely, and if we feel we can find out extra information we will look at interviewing Simon Cope," Collins told The Telegraph. "We are also open to calling people back to ask them further questions. At this stage we are not ruling anything out."
Collins accepted that Brailsford's alleged behaviour towards the Daily Mail raised further questions.
He told The Times: "It adds to a picture which doesn't seem to make any sense. Why should Dave Brailsford go to such lengths not to reveal what was in the package and try to prevent the story being published if what was in that package was completely innocent?
"He appears from this report to be trying to stop the line of inquiry. If he knew it was Fluimucil why did he not say so straight away?
"If he didn't, why did he try to close down a legitimate investigation? He needs to explain why he said what he did, and what he knew about the package at the time. Then we can judge whether it was rash and foolhardy or more serious than deliberately trying to close down the investigation."
