Cameron's US visit appears to have been made up of a series of photo opportunities. Above, David Cameron and Barack Obama eat hot dogs while watching a basketball game.
Here they are sitting in the stands at the same game, which took place at the University of Dayton Arena in Dayton Ohio.
Obama greets enthusiastic fans after the game, while Cameron looks on. (You can watch a video of the rather awkward incident here ).
This is the money shot: Cameron and Obama stepping off Air Force One as they arrive in Ohio. Breathless commentary yesterday made much of the fact that Cameron is the first non-US leader to go on board the iconic plane with Obama.
Looks like a shared romantic moment, but actually isn't. Here, Obama and Cameron walk towards Marine One before travelling from Washington to Ohio.
