Food and fuel inflation could lead to riots in poorer countries, the Guardian reports Ngozi Okonjo-Iweala as saying.

"The impact on food prices and hunger this year and next could be substantial. Food and energy are the two biggest items in the consumption baskets of poor people all over the world. It is poor countries and poor people within poor countries that will suffer the most.”

She said that 35 African countries were directly affected and said that policies to mitigate the impact of higher prices should be put in place.

This week we reported that Egypt set a fixed price for unsubsidised bread, with the aim of controlling rising food prices due to the disruption to the wheat supply caused by the war.
