How do you handle President Trump? Is China a national security threat to the UK - and should it be allowed its new 'Super Embassy' in central London? And could a future government potentially strike a migrant returns deal with the Taliban? These are just some of the questions Amber, Mark, and Marc put to Mark Sedwill - the UK's former National Security Adviser and Ambassador to Afghanistan - in a rare and wide-ranging interview.

Hear his candid view on the recent collapse of the Chinese spy trial, the terror threat to the UK in light of events in the Middle East, and anecdotes about how previous governments stopped migrants illegally entering Britain through the Channel Tunnel - and what this administration can learn when it comes to stopping the boats.
