Ukrainian President Volodymyr Zelensky is returning to the White House, where he will be briefed on President Trump’s Alaska summit with Russian President Vladimir Putin.

The vice-president upbraided him for ingratitude and he was accused of disrespecting the occasion by failing to wear a suit. This time around, weeks of coaching by European leaders paid off. Mr Zelensky thanked his host seven times in 50 seconds as cameras rolled in the Oval Office.

His last trip to the White House ended in a shouting match - so what will Ukraine's leader do differently today?

Ukraine's leader is scheduled to meet with President Trump and his advisers in the Oval Office alone before an expanded meeting with European leaders.

During their second meeting in the Oval Office this year, President Donald Trump said the U.S. would be willing to support European efforts to police any peace deal in Ukraine, while its leader, Volodymyr Zelenskyy expressed his gratitude and wore dressier clothes.
