The case against Christopher Cash, a former parliamentary researcher, and Christopher Berry - who have both consistently maintained their innocence - collapsed after the CPS said evidence could not be obtained from the government referring to China as a national security threat.
Former MI6 head Richard Dearlove says it looks like "something was done behind the scenes" to get the case against two British men accused of spying for China dropped.
