In the opinion of #Donald Trump, the new location of the #US embassy at Nine Elms site, near Battersea in #London was a bad deal.
The US embassy move was confirmed in October 2008, when President George W Bush was still in the White House.
The new embassy on the South Bank is a veritable fortress set back at least 100 feet (30 meters) from surrounding buildings, mostly newly-erected high-rise residential blocks, and incorporating living quarters for the U.S. Marines permanently stationed inside.
The British government has extended Trump an invitation for a state visit.
"The opening of the US Embassy is a matter for the US". In December, Johnson said he was looking forward to welcoming the president. She suggested a formal visit could still, but offered no details.
The US president, who has cancelled plans to visit Britain, was accused of being racist after questioning why his country should accept more immigrants from Haiti and "s***hole countries" in Africa rather than places like Norway.
In the meantime, the relationship between May and Trump has come under strain.
Khan had previously called on May to cancel the invitation after Trump retweeted anti-Muslim videos from a far-right Twitter account in November, accusing the US president of promoting a "vile, extremist group", The Associated Press at the time.
She said, in a rare public rebuke, "I am very clear that re-tweeting from Britain First was the wrong thing to do".
The London Mayor, Sadiq Khan, said on Friday that Trump had clearly "got the message" that many Londoners would not welcome his visit.
Local Labour MP Marsha De Cordova told Sky News she was "pleased" Mr Trump would not be travelling to the United Kingdom because he was "really scared" of being met by a peaceful protest made up of hundreds of thousands of people.
But Johnson accused Khan and Labour leader Jeremy Corbyn of damaging US-UK relations with their vocal criticism.
Downing Street is said to be considering options for a visit later this year.
