Ellie Levenson, editor of the Fabian Review, has left to the join the press and communications team for the charity End Child Poverty.
Before joining the Fabian Review, where she worked for two years, Levenson was a reporter at The Lawyer.
Her journalistic career was boosted when she won a competition run by The Guardian. She and another journalist had to travel across the world in separate directions writing about a subject of their choice in each country they visited.
Levenson's chosen subject was sex and kebabs, each of which she sampled "to a certain extent".
Levenson has also freelanced for the New Statesman, The Guardian, Press Gazette and The Observer. She writes about social policy and cultural theory as well as opinion pieces and topical features.
Levenson said of her new role at End Child Poverty: "There are an estimated 3.6 million children living in poverty and EPC aims to end this by the year 2020 - a date pledged by Tony Blair.
"It is such an exciting and important campaign. I feel that if we push the Government hard enough, we can really make a difference.
"I look forward to raising public awareness and ensuring the issue remains high on the domestic policy agenda."
ECP director Jonathan Stearn said: "Ellie brings with her the passion, creativity and experience that will help drive ECP forward in its quest to end child poverty once and for all."
Levenson will be replaced at the Fabian Review by Jonathan Heawood, a former deputy literary editor of The Observer. Heawood freelances for a range of publications, including The Observer, the New Statesman, The Independent on Sunday and The Times Literary Supplement.
He will join Fabian Review in July.
