Speculation that newly declassified US intelligence will contain smoking-gun evidence.

Three years on from the start of the pandemic, the FBI - the US domestic intelligence agency - reveals it sees a lab leak in Wuhan as the most likely source of Covid. Weeks later, the US Congress passes a law requiring the country鈥檚 intelligence agencies to declassify information they have that potentially links the Wuhan Institute of Virology with Covid鈥檚 origin. What will it reveal? And, in our final episode (for now at least), what conclusions can we reach about that question that鈥檚 sparked so much controversy and acrimony: where did Covid come from?
