It can be argued that the Airbus Scandal (which occurred when Brian Mulroney was prime minister) was more serious than either the Pacific Scandal (when Sir John A. Macdonald was PM) or the Sponsorship scandal (when Jean Chrétien was PM). Do you agree Airbus was the most serious of the three? If so, why? If not, which do you think was the most serious: the Pacific or Sponsorship scandal? Please explain your reasons.
