A string of details about Monday's attack at an Ariana Grande concert at Manchester Arena that killed 22 people and injured over 100 others have emerged from US law enforcement sources before being released by British police or officials.
"The British police have been very clear that they want to control the flow of information in order to protect operational integrity, the element of surprise," Rudd told BBC Radio.
Asked if the leaks from US officials had compromised the ongoing investigation, Rudd said she "wouldn't go that far." But, she added, "I can say that they are perfectly clear about the situation and that it shouldn't happen again."
The US is one of Britain's key intelligence partners. Both countries share sensitive information as part of the "Five Eyes" alliance, which also includes Canada, Australia and New Zealand.
