Berlin (dpa) - Mecklenburg-Western Pomerania's Prime Minister Manuela Schwesig has called the grand coalition before renewed deliberations on the subject of ground rent to an agreement. "It is high time that we finally come to a bottom line in the interest of those affected," said the SPD politician of the German Press Agency. The land rent is an important contribution to the fight against old-age poverty and a key issue when it comes to the mid-term review of the Grand Coalition.
