The Kremlin’s top brass are trying to pass the buck over the ruble’s collapse. This rare public infighting shows just how precarious Russia’s wartime economy is.

• The Kremlin’s top brass are trying to pass the buck over the ruble’s collapse.
• President Putin’s chief economic adviser has blamed the weak ruble on the central bank’s policies.
• Russia’s central bank governor, Elvira Nabiullina, said the weak ruble is due to changing trade flows.

Russia’s economy is in such a mess that the country’s top officials appear to be pitted against one another in public.

The rare show of discord came amid a slump in the ruble, which has fallen about 20% against the US dollar this year. The Russian currency hit a 16-month low against the greenback earlier this week.
