I want to know the answer to the following question:
Who did Labour lose power in the election to?
All the background I'm provided with is that "Blair announced in September 2006 that he would quit as leader within the year, though he had been under pressure to quit earlier than May 2007 in order to get a new leader in place before the May elections which were expected to be disastrous for Labour.". Is that enough to answer the question?
