Winchester is a constituency [n 1] in Hampshire represented in the House of Commons of the UK Parliament since 2010 by Steve Brine, a Conservative. [n 2]
The constituency is in mid-Hampshire and comprises the northern bulk of the large City of Winchester District as well as Chandler's Ford and Hiltingbury in the Borough of Eastleigh. The largest settlement is Winchester.

1950–1955: The Boroughs of Eastleigh, Romsey, and Winchester, in the Rural District of Romsey and Stockbridge the parishes of Ampfield, Chilworth, East Dean, Lockerley, Melchet Park and Plaitford, Michelmersh, Mottisfont, North Baddesley, Nursling and Rownhams, Romsey Extra, Sherfield English, and Wellow, and part of the Rural District of Winchester.
1955–1974: The Boroughs of Romsey and Winchester, and parts of the Rural Districts of Romsey and Stockbridge, and Winchester.
1974–1983: The Municipal Boroughs of Andover and Winchester, the Rural District of Andover, and parts of the Rural Districts of Romsey and Stockbridge, and Winchester.
1983–1997: The City of Winchester wards of Bishop's Sutton, Bishop's Waltham, Cheriton, Compton, Durley and Upham, Itchen Valley, Littleton, Micheldever, New Alresford, Olivers Battery, Otterbourne and Hursley, Owlesbury and Colden Common, St Barnabas, St Bartholomew, St John and All Saints, St Luke, St Michael, St Paul, Sparsholt, The Worthys, Twyford, Upper Meon Valley, and Wonston, and the District of East Hampshire wards of Alton Holybourne, Alton North East, Alton North West, Alton South East, Alton South West and Beech, Farringdon, Four Marks, Medstead, North Downland and Ropley, and West Tisted.
1997–2010: The City of Winchester.
2010–present: The City of Winchester wards of Colden Common and Twyford, Compton and Otterbourne, Itchen Valley, Kings Worthy, Littleton and Harestock, Olivers Battery and Badger Farm, St Barnabas, St Bartholomew, St John and All Saints, St Luke, St Michael, St Paul, Sparsholt, The Alresfords, and Wonston and Micheldever, and the Borough of Eastleigh wards of Chandler's Ford East, Chandler's Ford West, Hiltingbury East, and Hiltingbury West.
Parliament accepted the Boundary Commission's Fifth Periodic Review of Westminster constituencies by making slight changes to this constituency for the 2010 general election, removing 11 mostly rural wards in and around Bishops Waltham to a new seat, Meon Valley. In return, Winchester gained four suburban and partially urban wards at the northern edge of Eastleigh. 
The chartered city sent burgesses (equivalent to advisory MPs) to the Model Parliament of 1295 and then to most Parliaments convened by the monarch in the medieval period and thereafter; its representation being fixed at two in number during this long period of English history. As is common, major disruption in representation caused by both infrequency of Parliaments convened and allegiance of the incumbents (whether a Royalist or a Parliamentarian) led to sporadic representation during the Protectorate of England and its Commonwealth which followed the end of most fighting during the English Civil War, in this case the stripping of wealth and status from Sir William Ogle followed his being supportive of the wrong faction at the wrong time.
The Redistribution of Seats Act 1885 reduced the narrow borough constituency that elected two MPs to only one, permitting the creation of new broader replacement seats in surrounding Hampshire countryside for two abolished boroughs: Andover and Fareham (also known as West and South Hampshire respectively).
The seat was a Conservative safe seat in terms of majority and length of time held from 1950 until 1997.
At the 1997 general election the incumbent MP Gerry Malone of the Conservative Party was defeated by Mark Oaten of the Liberal Democrats by just two votes. This was the closest result in any of the 659 constituencies contested at the 1997 general election, followed by the Liberal Democrats 12 vote majority (also over the Conservatives) in Torbay.  Malone petitioned the result and it was declared void by the High Court on the grounds of mis-stamped ballots having altered the outcome, necessitating a by-election. This was won definitively by Oaten with a very large majority of 21,556, in an election that saw the Labour vote collapse to 1.7% hence the candidate, Patrick Davies, losing his deposit.
The events of 1997 swung the constituency strongly away from its usual status as a fairly safe Conservative seat.
The candidacy of Richard Huggett in both 1997 elections as a "Literal Democrat" candidate led in part to the creation of the Registration of Political Parties Act 1998.
Oaten stood down at the 2010 general election and was replaced as Liberal Democrat candidate by Martin Tod. Following significant boundary changes, Tod was defeated by Conservative candidate Steve Brine, who took the seat with a majority of 3,048 votes. Brine held the seat in 2015, 2017 and 2019, although in 2019 his majority was reduced to just 985 votes over Paula Ferguson of the Liberal Democrats, making Winchester one of the most marginal seats in the UK.
The ancient capital of Wessex, Winchester is a cathedral city with the arts and humanities-oriented University and an affluent population. Poverty is very low, and the population is a mixture of students, academics, London and Southampton commuters, and those employed locally in high-tech and creative industries. 
The only other large settlement in the constituency is Chandler's Ford which has over 21,000 residents and is largely a dormitory town. The constituency also includes several villages, mostly to the north and east of Winchester, including Micheldever, New Alresford and Kings Worthy. Much of the rural territory previously in the constituency was moved to Meon Valley from the 2010 general election.
Workless claimants who were registered jobseekers were in November 2012 significantly lower than the national average of 3.8%, at 1.4% of the population based on a statistical compilation by The Guardian .
