Drumev was a supporter of Russia and opposed openly the foreign policy of the Regency (1886–1887), the first Stefan Stambolov regime (1887–1894) and Prince Ferdinand's regime, which led to repressive measures against him.
He also served as one of the regents of the Principality of Bulgaria after Prince Alexander of Battenberg's abdication (1886–1887) and was Minister of War in Stefan Stambolov's government (1887–1891).
