How is Cameron's comeback coming along?

As problems in the Middle East and war on the continent dominate the headlines, David Cameron has been front and centre in his new role as foreign secretary. Is his experience coming in handy? Is he Rishi's 'prime minister abroad'? 

Katy Balls speaks to Craig Oliver, director of communications at No. 10 during the Cameron era, and Sophia Gaston, head of foreign policy at Policy Exchange.
