Churchill told Stalin he could settle the issue with the Poles once a decision was made in Tehran, however he never consulted the Polish leadership. When the Prime Minister of the Polish government-in-exile Stanisław Mikołajczyk attended the Moscow Conference (1944), he was convinced he was coming to discuss borders that were still disputed, while Stalin believed everything had already been settled. This was the principal reason for the failure of the Polish Prime Minister's mission to Moscow. The Polish premier allegedly begged for inclusion of Lwów and Wilno in the new Polish borders, but got the following reply from Vyacheslav Molotov: "There is no use discussing that; it was all settled in Tehran."
