A split between German Chancellor Angela Merkel and Finance Minister Wolfgang Schaeuble is widening over Greece as the funding standoff goes down to the wire, said people familiar with the matter.

Merkel is ready to make concessions to keep Greece in the euro because of geopolitical concerns, while Schaeuble is willing to let the country exit the euro unless its government takes measures to ensure the country’s long-term survival in the monetary union.

That divide is also reflected in Merkel’s parliamentary caucus, which is increasingly uneasy with letting the 41-member budget committee decide on disbursing any aid to Greece and is looking instead at a vote of the lower house of parliament on a deal that includes changes to previous agreements.
