LONDON, ENGLAND - JANUARY 30: Demonstrators hold up placards during a protest outside Downing Street against U.S. President Donald Trump's ban on travel from seven Muslim countries on January 30, 2017 in London, England. President Trump signed an executive order on Friday banning immigration to the USA from seven Muslim countries. This led to protests across America and, today, in the UK, a British petition asking for the downgrading of Trump's State visit passed one million signatures this morning.
