Query: What's another term for influential intermediary?
Context: Convinced that he needed a wasta, or an influential intermediary to promote his application above the others, Nasser managed to secure a meeting with Under-Secretary of War Ibrahim Khairy Pasha, the person responsible for the academy's selection board, and requested his help. Khairy Pasha agreed and sponsored Nasser's second application, which was accepted in late 1937.
