Protesters Gather In London To March In Protest Of President Trump’s U.K. Visit
A day of planned mass protests against President Donald Trump’s visit to the United Kingdom kicked off in dramatic fashion, as the U.S. President walked back a series of explosive comments about Britain’s leaders to a tabloid newspaper.
Apparently, Trump´s British Conservative poodle, Prime Minister Theresa May, arranged this. While her minority administration suffers defeat after defeat in parliament. While her Conservative party is hopelessly divided and stands to be trounced by the electorate during the 23 May European parliament elections … if these elections will go ahead.
