For the new series of Extreme World, Kemp met members of the Azov Battalion near Mariupol - which just months before had been seized by pro-Russian separatists. The country’s second largest sea port, the city is 10 miles from the front line, and its industry is vital to Ukraine's economy.

The commander of the civil defence for Mariupol is responsible for coordinating the protection of the city from the separatist forces who are based just 15km outside of the city limits.

"They are nationalists, that’s what they call themselves, but they are patriots first and foremost," she says of the militias.

"So we ask them 'please don’t leave the city. We will help you. We need you, because we want to live in Ukraine.' Having them here is crucial for us."

An Azov commander agrees, saying the militias are here to stay.

"When the Ukranian army was destroyed near Iloviask, Azov were the ones who held Mariupol. Now we are part of Mariupol. You can’t imagine one without the other."

And there is no shortage of new recruits – applications from members of far right groups around the country are piling up.

"Ukranians love Azov," he adds. "They are proud of Azov. People step aside and look up to you as a hero."

Azov are hoping to turn this rising tide of political sympathy into real political power – and this has already started to happen.

And while discontent with the current government grows – the influence of the far right only increases.

In October 2014 members of Azov and other similar organisations marched in their thousands through the streets of the capital Kiev. The Azov brigade marched with heavy metal music blaring out, shouting slogans, urging people to follow them.

"The shorthand for this demonstration is ‘we are here’," says Kemp. "They really are now a force to be reckoned with."

There seems to be little effort from the government to put a stop to the rise of the far right.

As the march gathered momentum – estimates put the crowd numbers at around 10,000, and as Kemp said, there were very few police on the streets. "What I've been told is this - they are simply too scared to stop this march."

Kemp visited Maidan Square where he witnessed a makeshift memorial to more than 100 civilians who were killed during the uprising.

"Any organisation that offers hope, a sense of patriotism and national pride - and also has members that are prepared to lay down their lives for this country - will have people rallying to its cause.

"But I can't help thinking the majority of people who laid down their lives in this square didn't do it to help the rise of the far right."

What is becoming more worrying is the increasing number of marches across the continent against what some see as the Islamisation of Europe.

The controversial anti-Islamic Pegida movement in Germany is proof that anti-immigrant xenophobia is on the rise; the movement has used slogans such as "Lugenpresse" that were regularly used by Hitler’s Nazi Party.

Following the Paris terror attacks, a fresh wave of far right sentiment has been spreading across Europe including Denmark, the Netherlands and Sweden.

Ukraine is not alone.
