On 24 January 2005, Tymoshenko was appointed acting Prime Minister of Ukraine under Yushchenko's presidency. On 4 February, Tymoshenko's premiership appointment was ratified by the parliament with an overwhelming majority of 373 votes (226 were required for approval). She is the first woman appointed Prime Minister of Ukraine.The Tymoshenko cabinet did not have any other members of Tymoshenko's party besides Tymoshenko herself and Oleksandr Turchynov, who was appointed the chief of Security Service of Ukraine. The ministers who were working with her took her side in the later confrontation with Viktor Yushchenko.On 28 July, Forbes named Tymoshenko the third most powerful woman in the world, behind only Condoleezza Rice and Wu Yi. However, in the magazine's list published on 1 September 2006, Tymoshenko's name was not among the top 100.Several months into her government, internal conflicts within the post‐Revolution coalition began to damage Tymoshenko's administration. On 24 August 2005, Viktor Yushchenko gave an Independence Day speech during which he called Tymoshenko's government "the best".Yet on 8 September, after the resignation of several senior officials, including the Head of the Security and Defense Council Petro Poroshenko and Deputy Prime Minister Mykola Tomenko, Tymoshenko's government was dismissed by President Viktor Yushchenko during a live television address to the nation. Yushchenko went on to criticize her work as head of the Cabinet, suggesting it had led to an economic slowdown and political conflicts within the ruling coalition. He said that Tymoshenko was serving interests of some businesses, and the government decision to re-privatize the Nikopol Ferroalloy Plant (previously owned by Leonid Kuchma's son in law Viktor Pinchuk) "was the last drop" that made him dismiss the government. On 13 September 2005, Yushchenko accused Tymoshenko of betrayal of "Orange Revolution" ideas. In his interview for the Associated Press, he said that during the time of her presidency at UESU, Tymoshenko accumulated an 8 million Hryvna debt, and that she had used her authority as prime minister to write off that debt. Tymoshenko has repeatedly stated that the mentioned amount was not a debt, but fines imposed by the Tax Inspection from 1997 to 1998, and that all the cases regarding UESU had been closed before she became prime minister.Tymoshenko blamed Yushchenko's closest circle for scheming against her and undermining the activities of her Cabinet. She also criticised Yushchenko, telling the BBC that he had "practically ruined our unity, our future, the future of the country", without rooting out corruption as he pledged to do and that the president's action was absolutely illogical.At the time, Tymoshenko saw a rapid growth of approval ratings, while president Yushchenko's approval ratings went down. This tendency was later proved by the results of parliamentary elections in 2006, when for the first time ever BYuT outran "Our Ukraine" party, winning 129 seats vs. 81, respectively. During the previous parliamentary elections of 2002, BYuT had only 22 members of parliament, while "Our Ukraine" had 112.The work of Yulia Tymoshenko as prime minister in 2005 was complicated due to internal conflicts in the "orange" team. According to Tymoshenko, President Yushchenko and Petro Poroshenko were trying to turn the National Security and Defense Council into the "second Cabinet of Ministers".Tymoshenko was succeeded as prime minister by Yuriy Yehanurov.
