Municipal administration Zhelyazkov held his first political position from 1998 to 1999, when he was Deputy Mayor for "Law and Control" of
Lozenets district. In 2003, he was appointed as Secretary of Sofia Municipality by then-mayor
Stefan Sofiyanski and was re-appointed to the role after the election of
Boyko Borisov in 2005. In 2009, after Borisov became prime-minister, Zhelyazkov was given the post of Secretary to the Ministerial Council, a position responsible for the administrative functions of the cabinet. As secretary to the cabinet under the
Raykov Government, Zhelyazkov was implicated in the so-called "Kostinbrod affair" surrounding the
2013 Bulgarian parliamentary election. A number of political parties, most notably the
BSP, alleged that around 350,000 ballots were printed illegally at a facility in
Kostinbrod with the authorisation of the caretaker government. As part of the investigation, Zhelyazkov was charged by the Prosecutor's Office for dereliction of his duty to oversee the proper printing of ballots. In 2014, the Sofia City Court found no evidence of wrongdoing by Zhelyazkov and ruled that he was innocent. From 2016 to 2017, Zhelyazkov served as a Public Administration and e-Government advisor to Prime Minister Boyko Borisov. In this role, he helped draft legislation for the implementation of e-government in Bulgaria and represented the country at the annual summit for open government partnership. On 30 September 2016, he was appointed Chairman of the newly-created State e-Government Agency. In this role, Zhelyazkov was responsible for overseeing the digitalisation of state services and the implementation of online solutions for government-issued documents. In October 2017, he was appointed as head of the Commission for the Regulation of Messages, responsible for overseeing the postal, radio, and e-signature state services.
Minister of Transport On 20 September 2018, Zhelyazkov was elected by the
National Assembly as Minister of Transport, Information Technology, and Communications. Shortly after his election, Zhelyazkov promised to work closely with the National Assembly and aimed to continue the programs started by Moskovski. In one of his first acts as Minister, Zhelyazkov ended the concession of
Plovdiv Airport following the withdrawal of the previous concessioners. Additionally, he chose to extend the deadline for the concession of
Sofia Airport. In November 2018, Zhelyazkov announced a change in the leadership of the
Bulgarian State Railways after a number of allegations of misappropriation of funds, as well as a lack of communication with the Transport Minister. During negotiations about the implementation of new amendments to the EU "mobility package", which aimed to regulate the status of inter-state logistical networks, Zhelyazkov opposed the proposed amendments for weakening workers' rights in the Bulgarian transportation sector and supported protests organised by them. In January 2019, Zhelyazkov announced that Bulgaria had managed to gain certain concessions about the status of Bulgarian lorry drivers during negotiations with EU institutions, although the concessions were judged as unsatisfactory by the lorry drivers union. Another challenge faced by Zhelyazkov were allegations by the Bulgarian Socialist Party that the contract for the concession of Sofia Airport was contrary to European legal practices due to undue favouritism towards a private company. He denied these allegations, highlighting that the contract only restricted the rights of the state. Ultimately, despite obstructions from the BSP, the airport was given to Sof Connect in June 2019. The choice of Sof Connect was challenged legally by a number of other participants in the process, for alleged uncompetitive practices of the Transport Ministry. The official contract of the concession was signed by Zhelyazkov on 22 July 2020. In February 2019, the bus drivers' union of Bulgaria threatened to hold a national strike due to unclear regulations surrounding the distribution of state subsidies to the sector. In response, a number of measures were announced to improve the working conditions of bus drivers and improve the distribution of state funds. Looking to reduce the bureaucratic burden on car registrations, he proposed a law allowing car owners to receive a technical inspection of their vehicles by private firms rather than exclusively by the automobile administration. The law was criticised by the BSP and some media outlets for allegedly enabling criminal activity. Zhelyazkov oversaw the construction of the
5G telecommunication infrastructure in Bulgaria. In 2020, the Ministry of Transport decided to resume the process for the concession of Plovdiv Airport for a 35-year period. In coordination with the Ministry of Education, Zhelyazkov attempted to reform the driving license examination requirements, including increasing the number of driving hours while reducing the theoretical requirements. The measure was opposed by driving schools, who alleged that the increased administrative burdens provided by the law, as well as the increase in driving hours, will lead to financial losses and over-work. Zhelyazkov defended the law, claiming that it would digitalise many elements of the examination process, thus in effect reducing corruption. Ultimately, the planned reforms were not implemented. As part of the government's efforts to combat the economic impacts of
COVID-19, Zhelyazkov authorised the implementation of the 60/40 wage scheme within the transport sector. Zhelyazkov's tenure as Minister of Transport ended following the dissolution of the
Third Borisov Government in May 2021.
Parliamentary activity and Speakership He was a Member of Parliament (
GERB-UDF) in the 45th, 46th, 47th, 48th and 49th National Assembly. On 25 April 2024, Zhelyazkov was removed from the post of
Chairperson of the National Assembly with 129 votes in favour, a day prior to the disbandenment of the
49th National Assembly before the
June 2024 Bulgarian parliamentary election. Zhelyaskov was selected as the list-leader for GERB-SDS for the
2024 European Parliament election, however did not take his seat within the European Parliament. He was nominated as the GERB-SDS Prime Ministerial candidate, following the June 2024 parliamentary elections. On 1 July 2024, Zhelyazkov received the first exploratory mandate for government formation by President
Rumen Radev following the
June 2024 Bulgarian parliamentary election. Zhelyazkov stated that he aimed to form a minority government and presented the composition of his cabinet before Radev on the day, thus fulfilling the first mandate. On 3 July, the National Assembly voted 138–98 to reject his proposed government, thus voiding the first mandate. == Prime Minister of Bulgaria (2025–2026) ==
