European leaders frantically tried to repair relations between Donald Trump and Volodymyr Zelensky following a very public bust-up at a meeting in the White House, which led to America suspending military aid and intelligence-sharing with Ukraine. During a big speech to Congress, Mr Trump mentioned an “important letter” that he had received from the Ukrainian president that talked of working together to achieve peace with Russia, which Mr Trump said he appreciated. In a social-media post Mr Zelensky admitted that the White House meeting did not turn out as intended, and offered to suspend long-range drone attacks, if Russia does the same.
