VATICAN CITY — The Vatican lashed out Saturday at the media for what it said has been a run of defamatory and false reports before the conclave to elect Pope Benedict XVI’s successor, saying they were an attempt to influence the election.

Italian newspapers have been rife with unsourced reports in recent days about the contents of a secret dossier prepared for the pope by three cardinals who investigated the origins of the 2012 scandal over leaked Vatican documents.

The reports have suggested the revelations in the dossier, given to Benedict in December, were a factor in his decision to resign. The pope himself has said merely that he doesn’t have the “strength of mind and body” to carry on.

On Saturday, the Vatican secretariat of state said the Catholic Church has for centuries insisted on the independence of its cardinals to elect their pope. Now, it said, the “pressures of public opinion” is in play in a bid to influence their vote.

“It is deplorable that as we draw closer to the time of the beginning of the conclave ... that there be a widespread distribution of often unverified, unverifiable or completely false news stories that cause serious damage to persons and institutions.”

It was issued as Benedict met for the last time with the Vatican bureaucracy before stepping down Thursday.
