The British government says it has been briefed by the United States about an expected release of American diplomatic files by the WikiLeaks website.
Prime Minister David Cameron's spokesman, Steve Field, says the government has been told of "the likely content of these leaks" by US Ambassador Louis Susman. Field declined to say on Friday what Britain had been warned to expect.
The Obama administration said earlier this week that it has alerted Congress and begun notifying foreign governments that the whistle-blowing website is preparing to release the diplomatic cables, which could damage U.S. relations with friends and allies around the world.
The release is expected this weekend, although WikiLeaks has not been specific about the timing.
