Whether the actual testimony will live up to the excited expectation remains to be seen, but either way the PM’s former chief aide Nigel Wright will testify today at the trial of Mike Duffy. As is known, Duffy is charged with bribery. It is not clear if Duffy is alleged to have asked for a bribe or is alleged to have been offered one. Wright is not charged. Legally, grounds for the charge seem elusive. And while the world may want to know what Stephen Harper knew, the issue may be that the prime minister isn’t on trial. It may reasonably be asked how what he knew relates to Duffy’s guilt or lack of it. Today will tell us some of that — maybe.
