In Britain, as many as 50,000 people took to the streets Saturday to protest Brexit—Britain’s plans to leave the European Union. This is protestor Poppy Somogyi.

Poppy Somogyi: “For me, it’s especially important, because I was too young to vote, and I felt that there are a lot of people my age like-minded who didn’t want this to happen, like we know it wasn’t a majority vote. And a massive factor is that we both—we’re both brother and sister. We come from a background of Hungarian immigrants. Our grandfather came here during the uprising. And just the kind of—the hate that you feel as a result of Brexit and as a result of this increase in xenophobia.”

Prime Minister Theresa May has announced she’ll send the formal paperwork, known as the Article 50 letter, notifying the EU of Britain’s exit on Wednesday. The paperwork will set off a two-year negotiation about the terms of the exit.
