Friedrich Merz, leader of Germany's CDU, is seeking support from the Green Party for a significant spending plan that aims to reform the country's debt brake, which limits government borrowing. The CDU and SPD propose to exempt certain defense spending from these restrictions and create a €500 billion fund for infrastructure. However, the Greens demand more focus on clean energy investments and have their own proposals. The CDU and SPD need Green votes to pass the reforms, but face opposition from other parties, raising concerns about the effectiveness of the proposed measures.
