The Guardian editor Alan Rusbridger has said it is remarkable that the "US president is responding to information put in the public domain by a newspaper".
He noted, however, that the British authorities are "closing their eyes and hoping [the story] goes away".
Mr Rusbridger added that the US president's proposed reforms would have a "deep knock-on effect" on British intelligence services.
