From East Hampshire - the wards of Clanfield and Finchdean, Horndean Catherington and Lovedean, Horndean Downs, Horndean Hazleton and Blendworth, Horndean Kings, Horndean Murray and Rowlands Castle
From Havant - the wards of Cowplain, Hart Plain and Waterloo
From Winchester - the wards of Bishops Waltham, Boarhunt and Southwick, Cheriton and Bishops Sutton, Denmead, Droxford, Soberton and Hambledon, Owslebury and Curdridge, Shedfield, Swanmore and Newtown, Upper Meon Valley, Whiteley and Wickham
The wards included are largely from parts of the former Winchester and East Hampshire parliamentary seats with some 600 voters from the Havant constituency which is otherwise unchanged.
When created, the notional result was based on ward data from the previous seats' general election results. The new constituency takes in territory from the then Liberal Democrat-held Winchester and Conservative-held East Hampshire with uncertain swing between the two parties . Estimates were that the Conservative majority if the seat had existed in 2005 would have been around 2,000 votes. At the 2010 election however, the seat saw one of the largest Liberal Democrat to Conservative swings (9.4%), and the Conservative candidate George Hollingbery was elected with a majority of over 12,000. A similar swing was recorded in the neighbouring Winchester seat, which was a Conservative gain. It would now take a swing of almost 12% for any party to gain Meon Valley and more than 24% swing for Labour.
