Both the Prime Minister and the Minister of Finance have said that they wish that they had recused themselves. It's hard to speak in terms of what might be the case, but I don't believe, because the program was being offered as a binary choice on whether to proceed or not proceed, that the program would have been any different if they had not been there. In retrospect, they have both said, given the potential for concern around a perception of favouritism, that this was reason enough for them to have recused themselves.
