‘They are isolated … they are alone’: Zelenskyy on Russia, Putin’s lies – and fighting back

In a wide-ranging interview, an upbeat Ukrainian president also discusses Donald Trump, King Charles, and how Kyiv is prepared to share its experience of drone warfare with the west

Sitting down with the Guardian in London, Volodymyr Zelenskyy seems cheerful. More than four years after Vladimir Putin's full-scale invasion, he believes Europe's biggest war since 1945 appears to be slowly turning in Ukraine's favour. The military situation is the most promising it has been for Kyiv for two and a half years, Zelenskyy says. We can't say Russia is losing this war. But we can say they are losing the initiative each day, day by day," he insists.

Over the past week the Kremlin has suffered a series of setbacks. Long-range Ukrainian drones have hit Putin's home city of St Petersburg, setting fire to oil terminals and sending smoke billowing above the skyline. Similar attacks have crippled occupied Crimea. A key supply road is littered with burning lorries and tankers and the peninsula seized by Russia in 2014 is experiencing severe fuel shortages.
