Five British Greenpeace activists and one Canadian have left Russia after being granted an amnesty from charges over an Arctic oil drilling protest.
Anthony Perrett, one of the six, said he was looking forward to returning to Wales after 100 days in Russia.
The six were among 30 people held on hooliganism charges and were released under a new Russian amnesty law.
