Klitschko, 35, began campaigning for mayor of Kiev shortly after his retirement in 2005. He lost the election to businessman Leonid Chernovetsky, but placed second with 26% of the vote. He was elected as a people's deputy to Kiev City Council, instead.
"I have my personal goals that I am pursuing despite any obstacles," Klitschko said in an interview with the Zerkalo Nedeli (Weekly Mirror) newspaper.
"I want to stay in the Ukrainian politics and become the mayor of Kiev," he said, adding that he would like to have the opportunity to influence the current political situation in the country.
The Ukrainian opposition has been recently calling for early elections of the city mayor and the city administration. The mayor is elected for the term of five years.
