Donald Trump has cancelled his visit to the United Kingdom, amid fears that he would be met with huge protests.
The American president claimed on Twitter that his reason for calling off the trip was his displeasure at Barack Obama having sold the current embassy for "peanuts" and built a replacement for $1.2bn.
Almost a year ago, Trump accepted an invitation to visit from Queen Elizabeth II, which was extended by Prime Minister Theresa May of Britain while she was in Washington shortly after Trump's inauguration.
Some British lawmakers questioned whether Trump would be welcome in London because of previous tweets and criticism of Muslims and his sniping at London Mayor Sadiq Khan in the aftermath of a terror attack in that city a year ago. "It seems he's finally got that message", Khan tweeted.
Former UKIP leader Nigel Farage said on BBC Radio 4's Today programme that it was disappointing that Mr. Trump had called off his visit.
Media reports said Secretary of State Rex Tillerson would probably replace Trump for the ribbon cutting ceremony.
As President Donald Trump waxed lyrical about why he would be axing plans to travel to Britain to open a new American embassy, a waxwork stand-in appeared more than ready to oversee the launch.
In a statement issued just a few hours after the announcement, Khan presumed that Trump "got the message" from many Londoners that he was not welcome over the pursuit of his divisive agenda, and characterized UK Prime Minister Theresa May's rash extension of the invitation as a mistake.
It comes after Theresa May initially extended an invitation for Donald Trump to come on an official state visit where the Queen would act as Trump's host.
Mr. Trump has already visited France, Poland, Japan, and China as US president, with little or no protest or opposition. However, the promotion of far-right group Britain First on Twitter was particularly sensitive in the country too.
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 US Marines permanently stationed inside. "That is the bigger picture here and I urge people to remember that".
