Greece's four-month bailout extension can expect to win wide support in the German Parliament after a large majority of lawmakers in Chancellor Angela Merkel's conservative bloc signaled their backing.

Parliament will vote Friday on the deal hammered out by eurozone finance ministers. It looks set to win support across the political spectrum.

Volker Kauder, caucus leader of Merkel's bloc, said an "overwhelming majority" of his lawmakers will back the agreement. In a test vote Thursday among the 311 conservative lawmakers, 22 opposed the bailout extension and five abstained.

Merkel's coalition with the center-left Social Democrats, who are solidly behind the deal, has four-fifths of the parliamentary seats.

Kauder said the conservatives "expect Greece to keep to what it has pledged."
