President Barack Obama made a surprise visit to 10 Downing Street

Former President Obama met with UK Prime Minister Rishi Sunak at 10 Downing Street on Monday, according to officials from Downing Street.

Obama and Sunak met on Monday afternoon at No. 10. They discussed a range of topics, such as international affairs and artificial intelligence (AI), according to a spokesperson from Downing Street.

The spokesperson mentioned that the meeting was included in Obama's visit to London alongside the Obama Foundation, a non-profit organisation established in 2014 by the former president and former first lady Michelle Obama.

On Monday afternoon, BBC News captured the former president on video. He approached the prime minister's Downing Street office, greeted reporters with a wave, and entered the building. According to Sky News, Obama arrived at approximately 3 p.m. local time on Monday and departed about an hour later.

Following his appearance at a technology festival in Belgium, Obama unexpectedly visited Laeken Castle to meet with Belgium's King Philippe and Princess Elisabeth, Duchess of Brabant. Obama did not mention the visit on social media; however, the Belgium Royal Palace shared a photo of the former president with the princess and king.

According to The Associated Press, Obama visited Downing Street multiple times during his two-term presidency, including during his 2008 campaign when he met with former British Prime Minister Gordon Brown in the garden of No. 10 Downing Street.

Obama's most recent visit to Downing Street occurred in April 2016, before the Brexit referendum. According to POLITICO EU, during that visit, the former president stated that if Britain were to leave the European Union, it would be placed at a lower priority for negotiating a trade deal with the US.
