Many thanks to Richard Kimber and Political Science Resources for generously making the election results for 1955 to 1979 available.

Note that the 2010 election is available as both the actual results (old constituency boundaries) and as data implied by the 2010 election results projected onto the revised constituency boundarieswhich were not used at the 2015 election. Similarly, the 2005, 2001 and 1992 elections are available both as the actual result, and as the result implied by the relevant boundary changes.

Details of the file format are given below.

• The number of constituencies varies:

• The Northern Ireland constituencies are included.
• Data is as at the date of each election, and does not reflect any subsequent by-elections.
• Implied election Data may omit the name of the sitting MP, though the 2001(Implied) and 2005(Implied) will give a suggestion where possible.
• The file contains one row per constituency, plus an initial header row.
• Each row contains a number of entries (in columns), which are divided from each other with semi-colon ";" delimiters.

The first five columns are always:

1. Name : the full name of the constituency
2. MP : the name of the MP elected in the election
3. Area : an integer code representing the area the constituency is in. Numbering goes from 1 (Northern Ireland) to 12 (South East). See area definitions for details.
4. County : county (or historic county or similar geography) containing the seat
5. Electorate : the integer number of voters on the roll in that election The next columns contain the votes for each party. The number of parties shown varies across the years and can be six-party (11 columns in total), or eight-party (13 columns in total). The meanings of the columns is also different for Northern Ireland. In Great Britain, the party columns are as follows:

1. CON : the integer number of votes received by the Conservative candidate
2. LAB : the integer number of votes received by the Labour candidate
3. LIB : the integer number of votes received by the Liberal Democrat candidate, or Liberal candidate pre-1988
4. NAT : the integer number of votes received by the nationalist candidate (SNP in Scotland, PC in Wales)
5. MIN : the integer number of votes received by a minor party candidate (separated from 'Other' to preserve rankings), or the SDP candidate 1983-1987
6. OTH : the integer number of votes received by all other candidates

In the eight-party format, there are 13 columns "UKIP-Green" format, which has the same first eight columns as the six-party format above, and then has two extra columns ("UKIP"/"Brexit"/"Reform" and "Green") after the "LIB" column.

1. UKIP / Brexit / Reform: the integer number of votes received by the UKIP, Brexit or Reform UK party candidate
2. Green : the integer number of votes received by the Green candidate
3. NAT : the integer number of votes received by the nationalist candidate (SNP in Scotland, PC in Wales)
4. MIN : the integer number of votes received by a minor party candidate (separated from 'Other' to preserve rankings)
5. OTH : the integer number of votes received by all other candidates

In Northern Ireland, the party vote columns have different meanings:

In the six-party format these are the precise definitions:

1. OUP/UUP : votes received by the OUP, UUP, or UCUNF candidate in Northern Ireland (1974 and later). For 1970 and earlier, these Unionists sat as part of the Conservative party.
2. SDLP : votes received by the SDLP candidate in Northern Ireland
3. DUP : votes received by the DUP candidate in Northern Ireland
4. SF : votes received by the Sinn Fein candidate in Northern Ireland
5. MIN : the integer number of votes received by a minor party candidate (separated from 'Other' to preserve rankings)
6. OTH : the integer number of votes received by all other candidates, including Conservative and UKIP

And similarly in the eight-party format:

1. OUP/UUP : votes received by the OUP, UUP, or UCUNF candidate in Northern Ireland (1974 and later). For 1970 and earlier, these Unionists sat as part of the Conservative party.
2. SDLP : votes received by the SDLP candidate in Northern Ireland
3. DUP : votes received by the DUP candidate in Northern Ireland
4. Alliance : votes received by the Alliance candidate in Northern Ireland
5. Green : votes received by the Green candidate in Northern Ireland
6. SF : votes received by the Sinn Fein candidate in Northern Ireland
7. MIN : the integer number of votes received by a minor party candidate (separated from 'Other' to preserve rankings)
8. OTH : the integer number of votes received by all other candidates, including Conservative and UKIP
