Prime Minister Edi Rama has rejected allegations of corruption, saying that throughout his years in public service he has never used political power for personal financial benefit.

Rama said he may have made mistakes during his career, but categorically denied ever receiving money or property in exchange for decisions or signatures made while serving as mayor of Tirana or as prime minister.

Addressing what he described as repeated allegations against him, Rama referred to claims that oligarchs or people linked to organised crime had benefited from his political influence.

He said such allegations could be repeated indefinitely, but argued that they had not been accompanied by evidence showing that anyone had given him money in exchange for a decision he had made.

"I may certainly have my faults," Rama said. "But what I can say with the greatest certainty is that no one can make me a party to anything that, during my 28 years and four months of public service, has affected the money, property or interests of Albanians."

Rama also rejected claims linking him to alleged corruption, criminal activity and property deals.

He said critics could make allegations about his alleged links to architects, criminals or businessmen, but maintained that no evidence existed showing that anyone had placed money in his possession or in his family's income in exchange for a decision he had signed as mayor or prime minister.

"Not a single piece of evidence that someone has put even a penny of their own money into my pocket or into my family's income, in exchange for a single signature of mine as mayor or prime minister, can ever be produced," he said.

Rama acknowledged that he was not "an angel" and could not claim to be infallible, but distinguished this from allegations that he had traded political power for money or property.

"The fault I can say with absolute certainty I have never committed is to trade, for money or property, the power that Albanians entrusted to me to revive Tirana and then Albania," he said.

He also maintained that his office had never been used to provide illicit favours or receive unlawful gifts.

Rama has been Albania's prime minister since 2013, having previously served as mayor of Tirana from 2000 to 2011.
