The British government has blamed the threat of mass protests for US President Donald Trump's decision to cancel a visit to London to open the new US Embassy, and warned that criticism of the White House risked harming US-British relations.
The U.S. Embassy says the new building cost $1 billion, funded entirely through the sale of other U.S. properties in London.
London Mayor Sadiq Khan, who has repeatedly clashed with Trump, welcomed the cancellation of the trip as well.
Some U.K. lawmakers had said Trump was not welcome in Britain after he re-tweeted videos from a far-right British group and criticized London Mayor Sadiq Khan following a terror attack a year ago.
Asked if it was a discourtesy to the Queen for Mr Trump to keep putting off the state visit, he replied: "An invitation has been extended and accepted and we will set out details in due course".
"As a junior foreign service officer, I signed an oath to serve faithfully the president and his administration in an apolitical fashion, even when I might not agree with certain policies. He was not going to get that kind of reception in London, which I believe led him to cancel that trip", West said.
Donald Trump can't make it to London so Madame Tussaud's museum has set up a waxwork Trump outside the United States embassy in Battersea. "The US is the biggest single investor in the United Kingdom - yet [London Mayor Sadiq] Khan & [Labour leader Jeremy] Corbyn seem determined to put this crucial relationship at risk. It seems he's finally got that message", the London mayor tweeted.
He noted how Mr Trump would have been met by "mass peaceful protests".
"A multi-disciplinary team of professionals considered over 170 criteria, to include physical security requirements, and determined that the Nine Elms site was the best overall location for the USA government", the statement added.
"The two countries remain very close in their foreign policies and work together closely".
As an American living in London, however, I was embarrassed: not, for once, because of the behaviour of my president, but for my British hosts.
"Beyond the disagreements between leaders and the optics of this cancellation, U.S. -UK relations continue to remain strong - largely because there are a wide range of institutional ties between the nations in military cooperation, intelligence, economics, and commerce that operate as normal despite the political storms that may arise", Mahaffee said.
British Prime Minister Theresa May's Spokesperson Max Blain said Vauxhall is a vibrant part of London and "home to many businesses", and not an "off location" as Trump had described.
On Friday, White House press secretary Sarah Huckabee Sanders refuted the speculation that the trip Trump canceled was an intended lower profile version of a state visit to Britain.
