Hordes of demonstrators began to converge in central London on Friday morning, intent on mocking U.S. President Donald Trump on his only full day of business with British leaders on what has been dubbed a "working visit" to the United Kingdom. 

London police say emergency services are outside the Natural History Museum in London after reports that a car has struck pedestrians. Police say a number of people have been injured and one person has been detained. Police said Saturday that more details would be released later.

President Trump is meeting with British Prime Minister Theresa May at the White House Friday. 

Concerns about the health of Queen Elizabeth II returned Sunday when she missed a New Year’s Day church service.
