(GermanPolicy.com) – SPD co-chairwoman Saskia Esken has emphasized that coalition partners of the SPD in a future federal government would have to support NATO, a strong, sovereign EU as well as a solid budgetary policy. This is non-negotiable, Esken said. In doing so, she increased the pressure on the Left party. Nevertheless, the SPD does not rule out a red-red-green coalition after the Federal Elections.
