Exclusive: Ukrainian president says ‘small mistake can break a big friendship’ in wide-ranging interview with Guardian

Volodymyr Zelenskyy has said the decision by some Reform UK councils to take down the Ukrainian flag was the kind of “small mistake that can break a big friendship”, as he underlined the significance of strong bilateral relations.

The Ukrainian president tempered his rare foray into UK domestic politics by stressing how much the two countries “need each other” in the battle against Russia, which he said posed a threat not only to Ukraine but to Britain too.

Keir Starmer says he will fight on as prime minister, but behind the scenes he is said to be thinking about his legacy. He’s talking this week about tech companies and the shape of a social media ban, but he is also focussed on resetting the UK’s relations with EU and defence.
