Director-general Tim Davie to warn world facing ‘all-out assault on truth’ as state-funded media operators broadcast ‘unchallenged’

The BBC director-general will warn that the retreat of its World Service because of funding cuts has helped Russia and China broadcast “unchallenged propaganda”.

In a speech at the Future Resilience Forum, a non-partisan meeting in London attended by international political figures, Tim Davie will discuss the global importance of the BBC World Service, which operates across more than 40 languages.
