History

Eastleigh constituency was created for the 1955 general election; before then Eastleigh itself had been in the Winchester constituency. It was a fairly safe seat for the Conservatives for nearly forty years until the death of its then MP, former journalist Stephen Milligan, in 1994. At the subsequent by-election, the Liberal Democrats gained the seat on a very large swing, and then held Eastleigh in the four following general elections (1997, 2001, 2005 and 2010), though with somewhat narrow majorities.

Chris Huhne, the MP from 2005 to 2013, was his party's environment spokesman in opposition, before becoming the Liberal Democrat senior spokesman for the Home Office (or Second Shadow Home Secretary). While in the previous role Huhne stood unsuccessfully for party leader in 2006 against Menzies Campbell and again in 2007 against Nick Clegg. Following the 2010 general election, Huhne joined the coalition government's cabinet as Secretary of State for Energy and Climate Change, but resigned as an MP in February 2013 after admitting perverting the course of justice over a speeding case.^[5] His resignation took effect from 5 February, and the following day it was confirmed that a by-election to fill the vacancy would be held on 28 February 2013.^[6] Mike Thornton retained the seat for the Liberal Democrats in the by-election. However, at the 2015 general election Thornton was defeated by the Conservative Mims Davies. Since then the seat has been held by the Conservatives.
