When Ivan Kostov became Prime Minister in 1997, Oresharski served under his administration as Deputy Minister of Finance, a position he held until the 2001 election, when he decided to lecture at the Higher Institute of Finances and Economics. In 2003, he was nominated by the UDF as a mayoral candidate for Sofia. In the same year, Oresharski left the UDF and was for a while part of the BZNS-NS, DP and "Gergyovden" coalition. In 2004, he was a member of the group that was in charge of drafting the economic reports for president Georgi Parvanov.
Finance minister
Oresharski returned to politics in 2005 as Finance Minister in the Socialist-led government of Sergei Stanishev, a position he held until Boyko Borisov replaced Stanishev as Prime Minister in 2009.
After the May 2013 parliamentary election, which was held earlier than initially expected because of the resignation of the Borisov cabinet, the latter's right-wing party, GERB, won a plurality. However, as it did not possess a majority in parliament and failed to secure backing from another party, the mandate was instead given to the second party: the Bulgarian Socialist Party. In May 2013 Oresharski was given a mandate to form a cabinet for the BSP by PresidentRosen Plevneliev. Following his announcement in media of his proposed cabinet there was a strong dislike amongst some towards Oresharski and his ministers, which led to anti-Oresharski cabinet protests even before the election of such cabinet. Green protesters organized themselves in May 27 and protested on May 28. Nonetheless the cabinet was elected and he became Prime Minister after a 120-97 vote in Parliament. Hours after the election new national protests were organized for 2 June 2013. However, national protesters reached thousands rallying on streets on 14 June after the appointment of Delyan Peevski, controversial figure, media mogul and previously investigated for corruption, for a head of Bulgarian security agency. After the first day of protests against his appointment, Peevski gave his resignation, but demonstrators continued demanding the resignation of the whole cabinet. The protests, varying in size from day to day, finally ended with the resignation of the cabinet one year later. On June 30, 2014, Bulgaria's fourth biggest bank KTB went bankrupt, amid accusations that the government had intentionally withdrawn the deposits of state-owned companies the previous weeks. The bailout would eventually cost the state budget $4 billion, and would double the public debt. On July 23, 2014, Oresharski submitted the resignation of his cabinet, a little more than a year after his appointment as Prime Minister. The next day parliament voted 180-8 to accept the government's resignation. Oresharski on a number occasions described himself as cognizant of the need to "have his resignation in his pocket from the very beginning of his tenure as Prime Minister".
