A wedding is a delicate thing. It is, one hopes, a one-time thing, and people want it to go 100% smoothly, even though most weddings do not. It doesn’t take much to cast a pall over a wedding, especially when someone from the outside tries to horn in or overshadow it.

You might imagine it’s even harder in the case of the insanely high profile wedding of a Prince. And Prince Harry is about to be married.

What is giving him, and the royal family at large the heartburn? Well the guest list, of course. But it’s not a matter of whether some cousin is at the wrong table or an old college friend has the wrong meal ordered. No, in this case, it’s a concern about the highest profile Twitter user in the world raising a stink over the highest profile wedding. We’re talking about Donald Trump, of course.

British paper The Sun has a story out this Christmas week about the fact that the Prince, who became chums with the Obamas during work on a project, may invite Barack and bride to the nuptials but not Donald Trump. Trump, it turns out, and you may not have known this, has sort of a huge and petty ego.

The Sun:

There are deep fears among senior Foreign Office and No10 officials that another perceived national snub will make it impossible for Theresa May to meaningfully engage with Trump.

A senior government source said: “Harry has made it clear he wants the Obamas at the wedding, so it’s causing a lot of nervousness.

“Trump could react very badly if the Obamas get to a Royal wedding before he has had a chance to meet the Queen.

You see, the Prince and the former President may be pals, but the Prime Minister and the current President … not so much. And that’s the problem. It’s not just that the ceremony could be overshadowed by an overcompensating temper tantrum on Twitter, but that actual relations between the two governments could be harmed, according to the Sun.

There was no mention in the article whether the U.K. was similarly worried last week before their decision to snub the United States and Israel and join countries like Syria, Venezuela, Turkey and Iran in condemning the President’s decision to move the American embassy to Jerusalem and recognize it as the capital of Israel.
