Donald Trump has arrived in the United Kingdom for his second official state visit. This is a rare honor of how much weight the UK is placing on its ties with Washington. The president and his wife, Melania, are being hosted by King Charles III at Windsor Castle, with formal ceremonies and meetings planned with Prime Minister Keir Starmer at Chequers.

The visit is designed to deepen relations between both countries, with a special focus on technology. Already, the two governments have signed what they’re calling the Tech Prosperity Deal. It is a sweeping agreement that covers artificial intelligence, quantum computing, and energy. Major companies like Microsoft, Google, Nvidia, and OpenAI are part of the pact. Microsoft alone is pledging around £22 billion for AI infrastructure in the UK. This is a chance to attract big investment for the British government, and position itself as a global place for high end technology.

But not everyone is celebrating. Trump’s arrival has caused protests across London and other cities. Demonstrators are voicing anger over his human rights record, his controversial stances on international conflicts, and his ties to Moscow. At one point, activists projected unflattering images of Trump and Jeffrey Epstein onto Windsor Castle.

Critics are also raising red flags about the tech deal itself. They warn that it could hand too much power to big tech companies and weaken protections for artists, workers, and data privacy. Even as the government promotes the agreement as a major economic win, campaigners are calling for safeguards that ensure ordinary people benefit too.
