A lively, super-confident Charlotte Church sits in front of me at the end of a series of grinding press interviews.

Hers is not just a face borrowed to front the anti-austerity movement, Charlotte knows the ins and outs and speaks with the passion and the conviction of a veteran.

I know she comes from a working-class Welsh community, but I am keen to learn what awoke her recent anger, leading her to speak at a series of protests including the upcoming June 20 March Against Austerity.

“It’s been building for quite some time,” she says.

“Just as you can so obviously see this poverty gap widen, it’s just so blatantly obvious and unjust.

“The richest people in our society have doubled their wealth since the recession and we are all told to pull our belts in and that’s not true and it’s also unnecessary.

“It’s that injustice, it’s nothing specific that I saw or that I’ve heard of.”

Bubbling with energy, she adds how she refused to accept the gloom and doom: “There could be a better future for our children.

“It doesn’t have to be this way — this consumerist, bloated, sad situation.”

We talk about celebrities’ role in mobilising people, which she admits is important “in this clickbait culture” to spread the message that austerity is not inevitable.

But above all Ms Church shows her witty and acute streak when I ask her if all the reporters’ questions about her own wealth stopping her from empathising with the poor becomes tiresome.

“I understand the reason for it and I am happy to answer, I’m happy to defend my position. It’s not like I’ve stolen it off anybody, I’m not a banker.”
