What does the MI5 boss really think about the collapse of the China spy trial?

Today, the MI5 boss has spoken out about his 'frustration' at the recent collapse of the China spy trial. But how will he really be feeling about this saga which has caused so much controversy for Keir Starmer and in national security circles? Amber reveals what Ken McCallum said when she saw the spy chief this week - and why the security services will be furious that the case has fallen apart.

Mark also explains why there is so much risk attached to any trial involving spying and national security - and what he learned about the scale of Chinese espionage from his trip to FBI HQ 20 years ago.

Plus Marc P gives his forthright view on whether Hamas can be persuaded to give up their weapons - and on whether Gaza's Arab neighbours really have the 'cojones' to provide a stabilising force to keep the peace in Gaza.

Later: why is Trump talking openly about the CIA's supposedly covert action in Venezuela? Is the US heading for war with the Latin American nation?
