When Duca was assassinated by the Iron Guard on December 30, 1933, Tătărescu's succession to the premiership effectively led to a change in political programs, as the new executive was open to collaboration with Carol. In the new context, Brătianu became an opponent of the monarch, and, in front of Carol's attempts to have the 1923 Constitution amended by authoritarian legislation, was a supporter of legal traditions; the Georgists also expressed reserve towards the outlawing of the Iron Guard, viewing it as a dangerous precedent. The PNL-Brătianu found itself in a bitter rivalry with the "young liberals", whose presence in the forefront blocked all negotiations between the two.
