I want to know the answer to the following question:
Which diplomat leaked information about the secret agreements?
All the background I'm provided with is that "So, that day, German diplomat Hans von Herwarth, whose grandmother was Jewish, informed Guido Relli, an Italian diplomat, and American chargé d'affaires Charles Bohlen on the secret protocol regarding vital interests in the countries' allotted "spheres of influence", without revealing the annexation rights for "territorial and political rearrangement".". Is that enough to answer the question?
Answer: yes
