Freelance journalist and film maker Kieron Bryan received a welcome home hug from his brother, Russell Bryan, as he arrived in London after spending four months in Russian jail.
Bryan travelled back to Britain with four Greenpeace activists who were also freed after being arrested by Russia during an Arctic protest.
Freed Greenpeace activist Alexandra Harris told ITV News' Libby Wiener that freeing protesters and journalists arrested during Arctic protests was "the easy way out for Russia" before the winter Olympics kick off.
Harris described the prison she was held in as "disgusting", adding: "I can't believe people spend years there before going for trial. As human beings we don't deserve that."

Alex Harris and Phil Ball, two of the four British Greenpeace activists allowed to leave Russia, have been pictured at Moscow airport. The protesters, plus a journalist, are set to arrive back in the UK later today.
The Europe minister David Lidington has said he is "delighted" that four British activists and a UK journalist who were being held in Russia over a protest in the Arctic have been allowed to leave - but reiterated the Foreign Office's concerns over the country's judicial system:
I am delighted that the British Nationals have been allowed to return to their families and friends.
This is a welcome step from the Russian Government.
We have provided consular support throughout the case and my Ministerial colleagues and I have repeatedly called for a fair and proportionate conclusion.
Whilst this move is welcome, issues of concern remain with the Russian judicial system.
The British Government continues to call on the Russian authorities to strengthen the rule of law, tackle corruption and promote independence of the judiciary.
A British man released from a Russian jail has said his ordeal "was definitely worth it" and that he would return to the country if needed.
Anthony Perrett, 32, will arrive in London today along with four other Britons after being held for over two months in a Russian jail after protesting against an Arctic offshore oil rig in September.
"It's been a very long 100 days. I'm quite eager to get back to Wales and sleep in my own bed and get back to work," he told BBC Radio 4's Today as he prepared to board the flight to the UK.
"The existence of humanity on the planet - what price can you put on that?," he said, insisting he would feel the same if he had been convicted and served a long jail term.
The 32-year-old said while the activists had not been mistreated, the facility they were held in was like a concentration camp.
"We weren't treated like prisoners of war. It had very much the razor wire and the barbed wire and the reinforcing bar which made up the cages. It had the aesthetic of a concentration camp, not the conditions of."
