New German President Frank-Walter Steinmeier has called for stronger French-German leadership to ensure the EU’s future one day after Britain triggered its exit from the bloc. Steinmeier said in a joint statement with French president Francois Hollande during a visit to Paris that “whether we want it or not, Germany and France will have to assume a greater responsibility… to build Europeans’ hopes.” He said the EU can be changed but remain “vital, indispensable.” French president Francois Hollande warned against “the trap of nationalism” in Europe and called on member states to show greater solidarity
