World leaders meeting in Paris on Thursday could give poorer countries access to hundreds of billions of dollars to tackle climate change.

Mia Mottley, Barbados’ first female PM, is leading the global fight for this money and tells BBC News that her tiny country urgently needs help.

Poorer nations want more money because they did little to cause climate change but face its worst effects.

They also struggle to afford expensive projects like renewable energy.

Insiders at the summit are expecting an announcement that a target for $100bn worth of a kind of international currency called Special Drawing Rights (SDRs) has been met.
