A diplomatic spat has erupted between Turkey and Italy, after prime minister Mario Draghi accused president Recep Tayyip Erdoğan of humiliating European commission president Ursula von der Leyen, and described him as a “dictator”.

Von der Leyen – the commission’s first female president – was left without a chair during a meeting on Tuesday with Erdoğan and the European council president Charles Michel met Erdoğan. The commission chief was clearly taken aback when the two men sat on the only two chairs prepared, relegating her to an adjacent sofa.
