All the deals that Martin is running around the country handing out are conditional on economic performance and surplus figures. That includes the $4.6 for the NPD, the McGuinty deal, etc, etc, etc,. The only deal it doesn't include is the Atlantic Accord.
The deal the NDP made specified that they would prop up the government on all confidence matters before the House until such time as the budget receives royal assent. That could be a very long time considering the 04/05 budget is still in the Senate.
