I want to know the answer to the following question:
Power then passed a political coalition headed by who?
All the background I'm provided with is that "As the senior partner in the new coalition, the PSdeG nominated its leader, Emilio Perez Touriño, to serve as Galicia's new president, with Anxo Quintana, the leader of BNG, as its vice president.". Is that enough to answer the question?
Answer: yes
