Next week, French Ambassador François Delattre and his wife Sophie L’Helias-Delattre bid adieu to Washington and head to New York. He’s been appointed as the French representative to the United Nations Security Council. With renovations at the palatial ambassador’s residence in Kalorama three months away from completion, invitees to Delattre’s last French National Day in D.C. were forced to make due with the posh Anderson House. On Thursday, the Dupont mansion hosted 300 Washington VIPs at a going away party fit for a diplomat with the keys to “the most coveted invitation in town.”

A new French ambassador to the U.S. has yet to be nominated, but a source at the embassy tells us one thing is certain: “The next [Bastille Day] is definitely going to be at the residence.”

After arriving fashionably late, Westmacott made a beeline for Delattre to congratulate his colleague, but settled for a wave over the crowd’s heads until later in the evening (Kate Warren for The Washington Post.)
