I want to know the answer to the following question:
With whom did Tito sign an agreement on September 28 1944?
All the background I'm provided with is that "On 12 September 1944, King Peter II called on all Yugoslavs to come together under Tito's leadership and stated that those who did not were "traitors", by which time Tito was recognized by all Allied authorities (including the government-in-exile) as the Prime Minister of Yugoslavia, in addition to commander-in-chief of the Yugoslav forces.". Is that enough to answer the question?
Answer: no
