In October 2011, Gyurcsány and other party members quit the MSZP to establish the Democratic Coalition (DK) under his leadership.

According to contemporary police documents, Gyurcsány's father was convicted on charges of minor crimes (low value thefts and fraud) multiple times.

After the political change in 1989, he became vice-president of the organisation's short-lived quasi successor, the Hungarian Democratic Youth Association (DEMISZ).

[9] Gyurcsány returned to politics in 2002 as the head strategic advisor of Péter Medgyessy, the previous prime minister of Hungary.

His government was forced to implement austerity measures to somehow manage the budget deficit, which was much higher than expected and had grown to an almost 10% of the GDP by the end of 2006.

These measures were heavily criticized by both the opposition, led by Fidesz, as being too harsh on the people, and by liberal economists, for not reducing spending enough on social benefits, including pensions.

[11] On the eve of the elections, before the results were known, President László Sólyom gave a speech in which he said that the solution to the situation is in the hands of the majority in Parliament.

[12] As Prime Minister, Gyurcsány was a strong advocate of the South Stream pipeline project, which aimed to supply Russian gas directly to the European Union (EU), bypassing transit countries such as Ukraine.

[4] In the search for a new prime minister, György Surányi became the frontrunner candidate for the post; however, on 26 March he pulled out of the race.

[20] On 14 January 2014, the Democratic Coalition and four other groups founded Unity, a political alliance with the aim of defeating Fidesz at the elections in the spring.

"[23] József Debreczeni, the biographer in question, originally reached the conclusion "regarding party connections and performance, the latter has been more important".

[25] A person named "Gyurcsányi" was mentioned by Attila Kulcsár, the main defendant in a high-profile "K&H Equities" money laundering scandal in Hungary.

In an article published on 2 April 2012, Pécsi Újság called into question whether Gyurcsány submitted a diploma thesis.

[27] István Geresdi, Dean of the Faculty of Sciences at the University of Pécs told Pécsi Újság that they were unable to find Gyurcsány's diploma thesis.

[30] Three days later, on 30 April Hír Tv announced that they have located and compared the reviews of both Rozs's and Gyurcsány's work, and found that based on the common errors and omissions, the two texts are likely to be identical, supporting the allegations of plagiarism.

Opposition claimed that the video was made public on purpose, as part of the election campaign, to gain popularity for the PM among young adults.

In an interview aired on TV2 during the 2006 parliamentary election campaign, Gyurcsány said that as a teenager, he "took part in confirmation for about two years" and even considered becoming a priest.

[40] On 13 January 2009, Dominique Strauss-Kahn, the managing director of the International Monetary Fund, travelled to Budapest to ask Gyurcsány about their agreement made in October, regarding the stabilization of Hungarian government spending.

His legitimacy was often questioned by opposition parties based on his withholding of information about the actual budget deficit in his 2006 re-election campaign.

[41] As a prime minister, Gyurcsány was said to be an advocate of the South Stream pipeline project, which is aimed to supply Russian gas directly to the EU, bypassing transit countries such as Ukraine.

Gyurcsány stated that it is an unlucky situation for a country to have only one supplier (Russia) of any resource, which in this particular case is natural gas.
