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.
