The Statement of Persons Nominated was published on 13 February and confirmed 14 candidates for the by-election. The defending party, the Liberal Democrats, nominated Eastleigh Borough Council councillor Mike Thornton. Maria Hutchings, the Conservatives' candidate at the General Election, was chosen as the candidate for the by-election on 7 February. Hutchings came to prominence in 2005 when she interrupted a live television phone-in with the then Prime Minister Tony Blair. She said that she would vote for Britain to leave the EU and would have voted against gay marriage. She also identified as pro-life and says that she is not a "Tory toff". The Labour Party chose author and broadcaster John O'Farrell as its candidate on 12 February. Having received during the campaign negative coverage of selected quotations from a book he wrote in 1998, in which he recalled the Brighton bomb attacks against the Conservative Party and then Prime Minister Margaret Thatcher, O'Farrell reflected after polling day that the experience was enough to put him off electoral politics for good. UKIP Eastleigh selected candidate Diane James, a Councillor from Ewhurst in Waverley, Surrey, who was elected there as an independent and subsequently joined UKIP. The party's leader, Nigel Farage, previously contested the seat at a by-election in 1994. While he initially said he would consider standing again, he decided not to after much media speculation. The English Democrats fielded Michael Walters, the South East Area Secretary of the party. The Christian Party candidate was Kevin Milburn. He said "I am standing in this election to allow voters the opportunity to show their disapproval of this Government over many issues, including their attack on marriage. The Government has upset vast swathes of the population with this ill-conceived Bill." The Monster Raving Loony Party, which stood in the 1994 by-election, selected its leader Howling Laud Hope as its candidate. On 8 February, the Trade Unionist and Socialist Coalition announced that it had chosen Darren Procter, secretary of the Southampton Shipping branch of the RMT union, as their candidate. Procter also serves on the National Executive Committee of RMT. He stood on an anti-austerity platform. The National Health Action Party, a new party founded in 2012 in response to the Coalition Government's healthcare reforms, selected Dr Iain Maclennan, a local doctor and former Royal Navymedical officer, as their candidate. Independent candidate Danny Stupple stood in protest at gay marriage and what he describes as the party "machine" pushing it through Parliament. The Wessex Regionalist Party fielded the party's president, Colin Bex, as its candidate.

Result
The Liberal Democrats' win was their first in a by-election since Dunfermline and West Fife seven years earlier. It was also their first by-election win under the leadership of Nick Clegg. The UKIP vote was their highest yet in any parliamentary election, and was the fourth time the party had come second in a by-election. At the time, it was also the closest UKIP had come to winning a Westminster seat. With less than 7% of the vote separating the top three candidates, it was the closest three-way result in an English by-election for over 90 years. It was also the first time since the 1989 Richmond by-election that Labour had come fourth while in opposition.
