The letter is addressed to the editors of The Times and Le Monde.

BR contests the claims made by "Bulgarian writers and artists" who have contradicted BR's previous claim of "the annexationist tendencies of the Bulgarian government". In particular BR focuses on "philosopher" Panayot Guindev, calling him "... an imbecile who tries in vain to put into order what he does not understand in the service of an illiterate dictatorship."

Also present is a copy of the letter, document .177166, TL(CAR). The copy is identical to the first TL(CAR) except it is also signed by Jean-Paul Sartre, Vladimir Dedijer, and Laurent Schwartz.

There is also a one-page copy of the letter, document .177167, TL(TC).

The copy appears to be a draft as it is edited and contains: "Odeon 8653 French text" at the top of the letter, and "M. Olle Wivek—Denmark. 3 days then Belgrade. Before 1" at the foot of the letter.
