Protesters on Monday gathered in London outside Lancaster House, the site of the first UK-EU summit since Brexit, urging Britain to return to the European Union. Demonstrators waved UK and EU flags, holding signs reading "Choose Europe" and "The Best Deal is with EU," while chanting "We all live in a Brexit tragedy," as they urged the government to rejoin the bloc. Britain and the EU reached a wide-ranging agreement on Monday, which is expected to generate nearly 9 billion pounds (about 12.02 billion U.S. dollars) for the British economy by 2040, Downing Street announced. The deal was unveiled ahead of the summit, which was hailed by both sides as a "historic moment." European Commission President Ursula von der Leyen called the agreement a "new chapter" in the relationship, as the two sides seek to reset ties after years of post-Brexit friction.

This is my home. I still don't get to have a say here, and also, the goalposts are changing from government to government on our rights. Only last week, we heard from Keir Starmer that now it might take 10 years for someone like me to be able to naturalise as a British citizen. It's put so many people in feeling like we're really alienated."; [SHOT OVERLAYING SOUNDBITE] 6. Protesters; [SHOT OVERLAYING SOUNDBITE] 7. Various of protesters.
