UK spy agency had to ‘pre-bunk’ Russian propaganda over Ukraine war, GCHQ boss says

GCHQ director Sir Jeremy Fleming said release of details of Russia’s military build-up helped counter Moscow’s narrative

The conflict in Ukraine has represented a “sea change” in the release of secret intelligence to inform public debate, the head of the GCHQ spy agency has said.

Sir Jeremy Fleming said the release of details by western intelligence agencies of the Russian military build-up in the run-up to the invasion had helped counter Moscow’s narrative that Ukraine was threatening its neighbour.

However, speaking on the BBC Radio 4 Today programme, he acknowledged that it had proved more effective in the West than in other parts of the world.
