 The amendments established the roles of President and Vice President within the collective Presidency which would rotate between individual republics and provinces on an annual basis.However, it also defined a separate title of President of the Republic which could be conferred by the Federal Assembly unto Josip Broz Tito who would automatically preside over the Presidency as well (and thus delay the implementation of the President of the Presidency role).Therefore, the launch of the Vice Presidency of the Presidency in 1971 would be the first to carry out a rotation system.
