Following the death of Chaophraya Yommarat (Choei), the title was left vacant, as the government was undergoing structural reforms abolishing the chatusadom system. A committee of four officials was established to oversee its functions in the interim period, before a modern ministry was re-established, named Krasuang Nakhonban or the Ministry of Metropolitan Affairs, in 1892. Prince Nares Varariddhi was named the first minister. In 1907, he was succeeded by Phraya Sukhumnaiwinit, who was named Chaophraya Yommarat (Pan Sukhum) the following year. He was the last holder of the title; the ministry was subsumed into the Ministry of Interior in 1922.
