Here's the letter:
When you speak with US president Donald Trump you’re speaking on behalf of all of us. Don’t put our British values aside in order to strike a deal with the USA.
Thousands and thousands of citizens of the United Kingdom
Today, our prime minister, Theresa May, is meeting Donald Trump, the new US president. If thousands of us sign an open letter to her demanding she stands firm on the things we all agree on - opposing torture, rejecting racism and protecting our planet - Theresa May could be one of the first people in the world to stand up to President Trump.
