NDP Leader Jack Layton is waiting for an answer from the Liberal Party. Depending on how they respond to his demands on health care, the NDP may or may not continue to support the government.
Given that he will not be meeting with the PM (who has gone to Argentina) but will only be receiving a letter from Health Minister Dosanjh, I can't help but wonder if Layton is pushing the envelope farther than he should. At this point, it seems unlikely that the Liberals will cave in to his demands. It is far more likely that they will call the combined bluff of the Opposition Leaders, daring them to trigger an eleciton over the Christmas Holidays.
