Boris Johnson will call for countries to do more to tackle the "devastating" effects of climate change, as he launches a new partnership with five other countries and the United Nations.
The prime minister is due to announce the creation of the Adaptation Action Coalition formed with Egypt, Bangladesh, Malawi, the Netherlands and Saint Lucia.
It will work to turn international political commitments made through the UN into on-the-ground support for vulnerable communities.
