US President Donald Trump has made a 100% commitment to Nato, according to Theresa May.
ITV News Political Editor Robert Peston said: "He didn't actually confirm that, but I assume those words were agreed.
"It means an organisation vital to our security and defence is going to be supported by the new president".
To be clear, this was as benign and accident-free a start to a new "special" relationship as Theresa May and her advisers could have wanted.
Voice and body language expert Caroline Goyder writes for ITV News about the signals given off during the meeting between the two leaders.
In the past, Mr Trump has described the organisation as "obsolete" and questioned the contribution of some members.
