After more than a decade’s worth of special guest appearances on CBC documentaries and at parliamentary committees, Karlheinz Schreiber begins what could turn out to be his most pivotal role tomorrow when he takes the stand at the Oliphant inquiry–and he’s more than ready for his closeup, according to the Winnipeg Free Press. In a telephone interview, Schreiber vowed to “do his best” to shed light on the murky relationship between himself and the former prime minister, and still holds out hope that it may eventually force the RCMP to reopen the criminal investigation into the Airbus deal: “We all know it (the inquiry) is not a trial or a criminal case. […] But when you have an inquiry, you never know when it starts where it will go.” In the same interview, he revealed that he has submitted still more evidence to support his claims against Mulroney, although he wasn’t willing to give details, citing a confidentiality agreement with the commission, telling Canwest his “lips are sealed”. At least, until tomorrow morning when his testimony is slated to begin. After that? All bets are off.
