British Prime Minister Theresa May raised her concerns about intelligence leaks over the Manchester attacks with US President Donald Trump at the NATO summit Thursday, her spokesman said.
"The prime minister raised the issue of the intelligence leaks with the president while they were waiting for the family photograph to be taken," May's spokesman said. 
"She expressed the view that the intelligence sharing relationship we have with the US is hugely important and valuable, but that the information that we share should be kept secure."
