Travels In Euroland With Ed Balls sees the former politician explore the rise of populism in six different countries across Europe. He tells The Guide about the most shocking moments during filming - and shares his thoughts on the Labour leadership contest.

During his first foray into documentary-making, Ed Balls was wary of being too opinionated.

The 2018 series, Travels In Trumpland With Ed Balls, saw the ex-shadow chancellor walk in the shoes of a variety of supporters of US President Donald Trump.

“I wanted to listen, and not to judge, and try and understand, and I didn’t think it was my job, in the programme, to be the person who directly challenged the contributor,” the Norwich-born presenter, 52, reflects.

He took a similar tack with his new factual entertainment show for BBC Two, Travels In Euroland With Ed Balls, in which he explores the rise of populism in six different countries across Europe (Holland, Spain, Poland, Italy, France and Germany).

But, while filming this series, there were moments which “felt more dark and fearful”, he confides... partly, perhaps, because of the cultural and geographical closeness to the UK.

He recalls going for dinner at the house of a politician from the AfD (a right-wing to far-right political party in Germany).

“In the afternoon, I look at a poster which the AFD had used in the election. The poster is a pregnant white woman, and the slogan is ‘New Germans? We can breed our own’, and he has made a speech saying we should eject 200,000 migrants a year.

“I go and have dinner with him, we have a long conversation. It’s quite a challenging conversation, I didn’t particularly enjoy it. I wasn’t going to go in and stir the mash with him.

“I felt as though I needed to be a bit apart, and that was different from some of the times in Trumpland. So, there are moments where I’m a bit more cautious.”

In the first episode, the affable former politician is in Holland, where he explores how cultural issues, “which go to a sense of national pride and identity”, can then be used by Trump-like populists to divide and get traction.

In Dutch tradition, Sinterklaas (St Nicholas) has a sidekick named Zwarte Piet, or Black Pete, who usually appears as a blackface character.

Balls goes on set for a film about the character, who is said to go back centuries, and today still appears in parades across the country on December 5, the Dutch St Nicholas holiday.

“I had a sense it was going to be a challenge,” he notes. “But, actually, I had no idea there was going to be scores of these ‘Black Petes’, and they were all going to be white, and it was quite slapstick.”

Later, he elaborates frankly: “Your first reaction is to recoil, and I think, intellectually, I didn’t shift from that.

“But, at the same time, you come to understand why it’s so hard for the majority of Dutch people who are involved in this and why it’s such a potent issue for populist politics, because (Geert) Wilders (leader of the Party for Freedom - a nationalist, right-wing political party in the Netherlands) basically says, ‘You should be proud to be Dutch’, and for Dutch people and their kids, who grew up with this, they think, ‘Well, I don’t want to not be proud of my childhood or my Christmas traditions’.”

We move on to the state of politics in the UK right now. Asked how hopeless he feels about it, he seems a little unsure of how to answer, omitting a high-pitched “um”, before pausing, to gather his thoughts.

“Well, I worry about our societies allowing politics to drift to the sort of populist position where, if we disagree, I don’t simply disagree with you, ‘I condemn you, because you are bad and you are wrong and immoral’. That every time that somebody says they disagree with a decision, they say, ‘It’s because it’s the elite who’s trying to do this to you’. That consensus is a dirty word... that if we agree that somehow we are selling out,” he suggests, calm but direct.

“You know, if I say the national minimum wage was a good policy and the Tories end up agreeing with it, and therefore it became consensual, does that mean that by definition this was a Tory-lite policy and a sell-out?”

Balls spent 20 years in politics, best known as Gordon Brown’s right-hand man after serving as his chief economic adviser prior to becoming an MP himself in 2005.

The father-of-three, who is married to fellow politician Yvette Cooper (she has been MP for Normanton, Pontefract and Castleford since 2010) spent ten years as an MP in Yorkshire. He lost his Morley and Outwood seat in 2015.

Following Jeremy Corbyn’s decision to resign as leader of the Labour Party, MPs are currently throwing their name into the ring. The battle is set to continue until April 4, when the new leader will be announced.

Four women have declared for the top job at the time of writing, including shadow foreign secretary Emily Thornberry, shadow business secretary Rebecca Long-Bailey and backbenchers Jess Phillips and Lisa Nandy.

Discussing the idea of a woman heading up Labour, Balls points out: “It’s not good that the Conservative party have now had two women prime ministers, and the Labour Party is yet to have one. Because Labour has had two short-lived female leaders, but never elected, and never as prime minister. So, let’s hope.”

But he won’t let on who he personally thinks should be leader, saying he doesn’t think there’s a front runner.

Travels In Euroland With Ed Balls starts on BBC Two on Thursday January 23.
