Charges against 29 Greenpeace activists, including two New Zealanders, who faced prison in Russia have been dropped following a Kremlin amnesty.
A Greenpeace spokesman in St Petersburg said the case against the remaining activist, Italian Cristian D'Alessandro, was expected to be dropped at a hearing today.
The "Arctic 30" were arrested three months ago over a protest against oil and gas drilling in the Arctic. They faced seven years in jail under hooliganism charges.
Greenpeace said it was asked to attend a meeting at Russia's investigative committee, where the criminal case against 29 of them were "dropped en masse".
However, the group of 28 activists and two freelance journalists have one more hurdle to jump before they can leave the country - securing exit visas.
