Actress Jane Fonda criticises US President Richard Nixon after returning from her controversial visit to Hanoi during the height of the Vietnam War in this newly-released archive footage.

In the news reel shot in Paris in July 1972, she says it will "take years to wipe off the blight" on America caused by the war. Her trips earned her the nickname "Hanoi Jane".

The rare footage is part of a "lost archive" from the 1960s and 70s recently uncovered in London. It is being restored by the Associated Press.
