After finishing The Night Agent ( which we both enjoyed ) we segued into
The Diplomat
which we have now just finished.
Plenty to enjoy, aided by "Location Porn" and "Opulent Interiors" ( it is set in the UK) .
Two prime examples being the new Embassy of the United States, London,
and The Ambassador's Residence, Winfield House, which although they correctly describe as being situated in Regents Park, and having "The second-largest private garden in London after that of Buckingham Palace.", The Skyline you see in the wide exterior shorts, while of London, is not one you would see from Regents park.
A bit of sleuthing (they didn't reveal all the filming locations in press releases ) revealed it to be Wrotham Park . I'll let them off.
Full marks for that ending
I'll let @Sherwood neither confirm or deny the accuracy of having to manage politicians with their own agenda.
