Theresa May is expected to call for action to prevent terrorist groups using the internet to spread propaganda and information, and she will also push for other countries to do more to tackle climate change.

Although it is not on the agenda, the leaders will also be concerned about the mounting tension over Iran’s activities in the Gulf and the fragile nature of the deal aimed at preventing Tehran developing nuclear weapons.
