British Prime Minister Boris Johnson was caught playing Farmville on his iPhone during a top-level meeting with US President Joe Biden. The two leaders were discussing the ongoing Brexit negotiations when Johnson’s attention wandered and he started playing the popular farming game. Biden was not amused, and berated Johnson for his lack of focus. “You’re supposed to be negotiating a trade deal with me, not playing Farmville,” he said. “I don’t even know what that is, but it sounds like a total waste of time.” Johnson tried to downplay the incident, saying that he was just taking a “quick break” from the negotiations. But Biden was not convinced, and demanded that Johnson put away his phone and focus on the task at hand. The incident highlights the growing rift between the two leaders, who have been at odds over the Brexit negotiations. Biden has repeatedly criticized Johnson’s handling of the talks, and has even threatened to pull out of a potential trade deal if Britain does not “get its act together.” For his part, Johnson has been trying to keep Biden happy, even going so far as to play American games like candy crush on his iPhone during their meeting.
