Their confirmation has been brought forward in the hope that they will have taken up their respective posts by the Fourth of July, according to a U.S. official.

Tuttle's plum London assignment has been vacant for nearly three years: his predecessor, millionaire horse breeder Will Farish quit the job early amid criticism from the British press that he had been practically invisible.
