European stocks fell for the fourth time in five days as a leader in Greece’s coalition government said he won’t support more spending cuts demanded by the region’s finance ministers.

George Karatzaferis, the leader of the Laos party, today said he couldn’t support the accord worked out for a new financing agreement in its present form.

Euro-area finance ministers yesterday refused to approve a second aid package because of a lack of assurances by Greek party leaders that they will stick to their commitments after elections due as soon as April. The ministers asked Greece to turn its budget cuts into law and identify 325 million euros ($429 million) in spending reductions.
