Steve Witkoff, Donald Trump's Mr Fix it on Gaza, Ukraine and now Iran, is in Paris alongside Marco Rubio. Sticklers for protocol would normally insist that the US Secretary of State is the bill topper of this diplomatic tour … but these aren't normal times. Does the 68-year-old former New York real estate mogul hold sway?

And can he do better than career policymakers? When Witkoff picks up on Kremlin talking points, does it mean that Washington has turned on Ukraine for good? Who in Europe can keep Witkoff and Trump onside?

Perhaps French President Emmanuel Macron, or Italy's prime minister? The far right's Giorgia Meloni, who was the only EU leader present at Trump’s inauguration, is back at the White House. Does she soon face a moment of choice on Ukraine, NATO bases in her own country and tariffs?
