Article: On 16 June 2006, it was announced that Everton had entered into talks with Knowsley Council and Tesco over the possibility of building a new 55,000 seat stadium, expandable to over 60,000, in Kirkby. The club took the unusual move of giving its supporters a say in the club's future by holding a ballot on the proposal, finding a split of 59% to 41% in favour. 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.
