The 1972 election is commonly regarded as an indirect referendum on Chancellor Brandt 's Ostpolitik ( Eastern Policy ) , which called for normalized relations with East Germany and the Soviet Union , which Barzel vehemently opposed . On April 27 , 1972 , Barzel and the CDU / CSU called a constructive vote of no confidence against Brandt 's government . Had the motion carried , Barzel would have succeeded Brandt as Chancellor of Germany . The implications of this vote were far - reaching . Brandt 's nitial reaction was that he , along with his policy of Ostpolitik , was finished . Several German trade unions went on strike in anticipation of his loss in the no confidence motion . However , the final tally received 247 votes ; 249 were needed to expel Brandt from office . Later , it was found out that two members of Parliament , Julius Steiner ( CDU ) and Leo Wagner ( CSU ) had been bribed by the East German Ministry for State Security . The government , in consideration of the fact that it had lost its parliamentary majority and that parliamentary work was stalled , reacted by calling new elections , which it won decisively . 1972 was the only time before 1998 and after World War II that the SPD outpolled the CDU , and it still represents the SPD 's high - water mark as a vote share . That year 's elections had the highest turnout ever . Within the CDU group of the German parliament , Barzel 's credibility suffered when it became apparent that he had lied about substantial outside income from work as a lawyer outside parliament .
