Montreal - Canada's Liberals showed a change of heart Wednesday that avoids another governance crisis as they threw their support behind Conservative Prime Minister 's budget and economic stimulus plan.

The change of heart came as Parliament reconvened this week after a recess that was forced by Harper in December over a budget stalemate.

To sweeten the deal, Harper has added a 40-billion-dollar economic stimulus package for Canada's slumping economy. His refusal to add such a measure in December provoked formation of a centre-left coalition led by the Liberal Party that threatened a vote of no- confidence.

Opposition leader Michael Ignatieff demanded certain conditions for his support, giving notice that Harper's government was on probation and would have to deliver timely updates on the results of the economic stimulus package.

As of late Wednesday, there had been no response from the Conservatives. dpa
