The discovery that I share an opinion with Donald Trump is a new experience for me, one which I don’t expect to reoccur soon, but when he took to Twitter last week to explain why he would not be opening his country’s new London embassy, I confess, I could rather see his point. **** I can’t argue with his description of the recently vacated former embassy, built in 1960, as “perhaps the best located and finest in London”. Extending a façade across an entire side of Grosvenor Square in Mayfair, this was the first purpose-built embassy in the capital.
