We're all story-telling creatures, and also I think that's the point about biography because the life is exemplary.

Eleanor Marx was her father's first biographer. All subsequent biographies of Karl Marx, and most of Engels, draw on her work as their primary sources for the family history, often without knowing it. I think if she'd been a son, she would have been referenced more.

Men want to destroy the women: you've become bigger than me, people love you more, you have a public platform, that's my space you're taking up. I can't just divorce you, I have to destroy you.

Before my book, the most common assessment of Eleanor Marx is "Yes, she's great but basically she's in the shadow of her father." Absolute bollocks. She fought him, she resisted, and she was not a kind of trocadateur of his ideas.

All of us are many different people over time. We have our childhood selves, people that we remember, but they're very different to our adult selves and the way that we create our own naratives is not that dissimilar, I think, to how a biographer structures their narrative of a life.

The trade unions in the UK are campaigning around zero-hours contracts, which isn't about feminism, but it's a feminist issue. Women are affected by zero-hours contracts, and the recession has and is affecting women more than men.

One of the key things about the entitlement and power of patriarchy, but also within feminism, is not that it's wilful nastiness. But you can't ask for permission. You can negotiate and you can bring people on board and you can build a base but you can't expect for it to be given.
