German Chancellor Angela Merkel will call on the country’s parliament to approve a third bailout for debt – marred Greece on Wednesday, but could face a rebellion from lawmakers within her own conservative ranks. Approval of the latest 86 billion euro emergency rescue plan for Athens is seen as assured given the 504 seats Merkel’s left-right “grand coalition” holds in the 631-seat Bundestag lower house. But grumbling has grown ever louder within her Christian Union bloc over lifelines thrown tot the Greek government of leftist Prime Minister Alexis Tsipras. Sixty of the 311 members in Merkel’s parliamentary group voted last month against authorising the start of negotiations with Greece on a new rescue package- defiance that was considered a blow to the Chancellor. Sources say the number of those defectors could rise this time. “If we are honest, this is hidden debt haircut (writedown) at the expense of our children and grandchildren,” conservative lawmaker Dagmar Woehrl said, signalling her decision to vote “no”. However, the Christian Democrats general secretary, Peter Tauber, warned that a vote against the bailout was “tantamount to stabbing the chancellor in the back” two years before the party fervently hopes to see her stand for a fourth term. Underlining the stakes involved, the party’s chief whip Volker Kauder this month vowed to impose sanctions on any dissidents in his ranks- a threat that may have backfired by antagonising backbenchers.
