The Vatican has blocked discussions over women’s rights at the UN climate summit following a row over gay and transgender issues, sources have told BBC News.

Pope Francis’ representatives have aligned with Saudi Arabia, Russia, Iran, and Egypt to obstruct a deal which would have provided more support, including financial help, for women at the forefront of climate change, Colombia’s environment minister told the BBC.

Charities including ActionAid said it is crucial a deal is reached as the UN estimates women and girls currently make up 80% of those displaced by climate change.
