I want to know the answer to the following question:
What percentage of fans were supportive of Everton's plans to build a new stadium in 2006?
All the background I'm provided with is that "Opponents to the plan included other local councils concerned by the effect of a large Tesco store being built as part of the development, and a group of fans demanding that Everton should remain within the city boundaries of Liverpool.". Is that enough to answer the question?
