Sunak has floated an idea that the U.K. could be a center for regulating the fast-moving technology, though no major news on that front is expected during his trip.

The prime minister’s spokesman, Max Blain, said Britain’s approach to regulation, “agile and able to adapt with the fast pace of this technology, makes the U.K. well placed to take a leading role here.”

Sunak is also likely to lobby for U.K. Defense Secretary Ben Wallace to become the next head of NATO after Secretary General Jens Stoltenberg steps down in September. The prime minister is expected to stress that the next secretary-general should be someone who “carries on Stoltenberg’s good work of modernization but also understands the importance of defense spending at this critical time.”

The comment could be seen as a subtle dig at another possible contender for the post, Danish Prime Minister Mette Frederiksen, who met with Biden in Washington earlier this week. Denmark has lagged behind NATO’s target for members to spend 2% of gross domestic product on military budgets by 2030.

Sunak is also due to meet U.S. business executives and hold talks with congressional leaders, including Speaker Kevin McCarthy, on Capitol Hill. On Wednesday evening he’ll attend a Washington Nationals baseball game – though he won’t throw out the opening pitch, to the disappointment of the British media.

Sunak stressed he was never meant to throw out the pitch at the game, which includes military bands and a flyover to celebrate of U.S.-U.K. ties.

“My sport is more cricket than baseball, in any case,” he said.
