Millions of children never see inside a classroom. Others drop out due to overcrowding, conflict, or simply because they're a girl.

A lot can get in the way of education. But from Leeds to Liberia, a love of learning is universal. Children know it's key to a world of possibilities.

And in the UK, we're improving early years learning and keeping childcare costs on the political agenda.
