Zlatan Brachkov was a famous political and business figure in the past. He was the first chairman of the newly established in December 1908 "Varna Technical Society", later renamed to "Engineering & Architectural Society of Varna".
He was member of the Executive Council of the Bulgarian Commercial Seafaring Society. He designed and reconstructed bridges over rivers and railway lines. He and his wife were active in charity work for the poor children. He took part in the Balkan and in World War One.
Zlatan Brachkov was elected Mayor of the town on 25 April 1922.
At the first meeting of the council he adopted the plan for building the sea baths with vision of the future of the town as a sea resort. He reviewed in detail the status of the social support services in town and set the scope of their activities - making known all existing factories, shops, outlets, etc., which apply hired labour, having statistics of the employed, solving the problems of charity, unemployment, etc. He found out that despite the loan of 2 million leva drawn, the municipal treasury was empty because there was no sufficient income. Many meetings of the municipal council were dedicated to the payment of the clerk's salaries, to buying good quality flour, to giving out municipal land to homeless people, to the need of a new loan for capturing more water for the town, to the development of certain streets, to the reduction of the prices of the basic food products, etc.
The Municipal Council paid attention to the education and culture, helped collect money for the construction of new schools in the suburbs. Improvements were made to Saedinenie Hall. The need to revive the artistic atmosphere of the theatre made the councillors bring back Stoian Bachvarov, a famous among the citizens of Varna director, actor and administrator. Mayor Brachkov initiated the renewal of the construction of the new theatre building.
On 23 October 1922, the communist councillors, 12 in number, resigned because of disagreement with the current municipal policies. As six more had left before, the Council was dismissed.
