Kuchma's victory in the election; but while his knowledge of Ukrainian noticeably improved, Kuchma did not follow through on his pledge to make Russian a state language during the 10 years of his presidency. In 2004 an election promise by Viktor Yanukovych (leader of the Party of Regions) to adopt Russian as the second official language might also have increased the turnout of his base, but it was rebutted during the campaign by his opponent (Viktor Yushchenko), who pointed out that Yanukovych could have already taken steps towards this change while he was a Prime Minister of Ukraine if this had really been his priority. During his campaign Yushchenko emphasized that his being painted as a proponent of the closure of Russian schools frequently made by his opponents is entirely baseless and stated his view that the issue of school language, as well as the churches, should be left to local communities.

In the wake of the 2006 Parliamentary crisis in Ukraine that fractured the governing coalition and returned Yanukovych to the Prime Ministership, the "Universal of National Unity" signed by President Yushchenko as well as the leaders of several of the most influential political parties declared that Ukrainian would remain the official state language in Ukraine. However, within a week after signing
