Russian authorities have dropped criminal charges against the first of 30 people accused of taking part in a Greenpeace protest in the Arctic.
The BBC has learnt the man is Anthony Perrett from Newport in Wales, and that he is now preparing to leave Russia.
He was in the group of 28 activists and two freelance journalists arrested in September as they staged a protest at a Russian offshore oil rig.
Greenpeace's Ben Stewart spoke to the BBC about the next hurdles facing them and the continuing campaign against Arctic oil drilling.
