Bahceli, leader of MHP, has repeatedly stated that he has three absolute requirements for coalition: 1. End of Kurdish peace talks; 2. Erdogan to behave as a constitutional ceremonial President (and not interfer with the Government); and 3. Resurrection of court proceedings over public corruption issues. If he sticks to his conditions that's going to be difficult for AKP to swallow - well conditions 2. and 3. anyway, AKP may welcome withdrawing from rapprochement with the Kurds and then blaming MHP for it.
