LONDON (Reuters) - A security guard at the British embassy in Berlin collected highly sensitive information for more than three years, including "secret" government communications with Prime Minister Boris Johnson, prosecutors told a London court on Monday.

David Ballantyne Smith, 58, scanned copies of a letter from two cabinet ministers to Johnson and other documents relating to "sensitive trade matters", prosecutor Alison Morgan told London's Old Bailey.
