The director of GCHQ, Sir Jeremy Fleming, is expected to say that Russian president Vladimir Putin may face revolt against his leadership, as his "exhausted" troops are now running out of supplies and munitions.
The head of the UK's intelligence, cyber and security agency, Sir Jeremy is to brand Putin as becoming "desperate" as Russia loses the war with Ukraine, stating that his decision to invade is now "backfiring" on Russia.
It has been reported that fighting-age Russians are trying to avoid being drafted into Putin's "war of choice".
