The 2015 Eastleigh Borough Council election took place on 7 May 2015 to elect 14, approximately one third of the members of Eastleigh Borough Council in England as one of the English local elections coinciding with the 2015 General Election. The local authority holds its elections in three years out of four ('by thirds').[1]
Liberal Democrats maintained their majority group, slightly reduced by two councillors to hold 38 of the 44 councillors across its 14 wards. The gains were of two seats to Conservatives and no other seats changed hands.
Sarah Bain later left the Liberal Democrats to sit as an independent councillor in August 2017.[2]
