European Commission President Ursula von der Leyen yesterday warned she is considering taking legal action against Berlin after a recent judgement by the Karlsruhe-based court. Last week Germany’s top court gave the ECB just three months to justify its flagship Eurozone stimulus scheme or face the Bundesbank being blocked from participating in it. In a statement, Mrs von der Leyen claimed the judgement had called into question the EU’s single currency and its joint legal system.
