The London meeting between former high commissioner Alexander Downer and Trump adviser George Papadopoulos was first reported by the New York Times in December 2017, reportedly revealing how Downer had been told by Papadopoulos that Russia had political dirt on Hillary Clinton.

Until now, the Australian government and Downer have refused to confirm or give any details about the meeting central to the beginning of the Trump-Russia investigation, repeatedly citing the need to preserve national security.

But in a letter sent to Australia’s Information Commissioner after a 15 month-long FOI battle with BuzzFeed News, a senior foreign official said his department was ready to confirm the meeting and release redacted documents, because Special Counsel Robert Mueller’s investigation was now finished.

“I have again reviewed these matters and, while standing by the validity of the original decisions at the time they were made, the Department has reassessed its position in relation to Mr Di Stefano’s three requests in light of the recent conclusion of the U.S. Special Counsel’s investigation into Russian interference in the 2016 Presidential Election,” the official wrote to Australia’s Information Commissioner Gillian Cameron.
