From 2015 to 2019 it was represented by Antoinette Sandbach, a former Conservative member who had the whip removed on 3 September 2019 and joined the Liberal Democrats on 31 October 2019.
Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat will be subject to major boundary changes, including the loss of the town of Winsford to the newly created constituency of Mid Cheshire, and the addition of those areas of Chester to the south of the River Dee, transferred from City of Chester (to be renamed Chester North and Neston). As a consequence, Eddisbury will be renamed Chester South and Eddisbury, to be first contested at the next general election.
It was re-constituted following the reorganisation of local authorities in 1974 by the Third Periodic Review of Westminster constituencies for the 1983 general election, with much of the constituency comprising areas covered by the previous version of the seat, transferred from the abolished constituencies of Nantwich, Northwich and Runcorn.
1885–1918: The Municipal Borough of the City of Chester, the Sessional Division of Broxton, and parts of the Sessional Divisions of Chester Castle, Eddisbury, Nantwich, and Northwich.
1918–1950: The Urban District of Tarporley, the Rural Districts of Malpas and Tarvin, in the Rural District of Northwich the civil parishes of Crowton, Cuddington, Darnhall, Delamere, Eddisbury, Little Budworth, Marton, Oakmere, and Wimboldsley, in the Rural District of Runcorn the civil parishes of Alvanley, Frodsham, Frodsham Lordship, Helsby, Kingsley, Kingswood, Mauley, Newton-by-Frodsham, and Norley, and part of the Rural District of Nantwich.
Minor losses, largely to the enlarged constituency of City of Chester, including Hoole.
On abolition, areas comprising part of the Rural District of Nantwich were transferred to Crewe; areas comprising the Rural District of Tarvin (incorporating the abolished Urban District of Tarporley and the Rural District of Malpas) transferred to Northwich; and small areas also transferred to the City of Chester and to the new County Constituency of Runcorn (including Frodsham).
1983–1997: The District of Vale Royal wards of Church, Cuddington and Marton, Davenham and Moulton, Forest, Frodsham East, Frodsham North West, Frodsham South, Gorst Wood, Gravel, Hartford, Helsby Central, Helsby North, Helsby South and Alvanley Ward, Kingsley, Mara, Milton, Oulton, Over One, Over Two, Swanlow, Tarporley, Vale Royal, Weaver, and Wharton, and the City of Chester wards of Barrow, Farndon, Malpas, Tarvin, Tattenhall, Tilston, and Waverton.
1997–2010: The District of Vale Royal wards of Cuddington and Marton, Davenham and Moulton, Gravel, Mara, Oulton, Over One, Over Two, Swanlow, Tarporley, Vale Royal, and Wharton, the Borough of Crewe and Nantwich wards of Acton, Audlem, Bunbury, Combermere, Minshull, Peckforton, and Wybunbury, and the City of Chester wards of Barrow, Farndon, Malpas, Tarvin, Tattenhall, Tilston, and Waverton.
Gained western parts of Crewe and Nantwich, including Audlem. Northern areas, including Frodsham and Helsby, transferred to the new constituency of Weaver Vale.
2010–2019: The Parliamentary Constituencies (England) Order 2007 defined the boundaries as:
The Borough of Vale Royal wards of Cuddington and Oakmere, Davenham and Moulton, Mara, Tarporley and Oulton, Winsford Dene, Winsford Gravel, Winsford Over, Winsford Swanlow, Winsford Verdin, and Winsford Wharton, the Borough of Crewe and Nantwich wards of Acton, Audlem, Bunbury, Minshull, Peckforton, and Wybunbury, and the City of Chester wards of Barrow, Farndon, Kelsall, Malpas, Tarvin, Tattenhall, Tilston, and Waverton.
Minor boundary changes, primarily due to local authority boundary changes.
However, before the new boundaries came into force for the 2010 election, the districts making up the county of Cheshire were abolished on 1 April 2009, being replaced by four unitary authorities. Consequently, the constituency's boundaries became:
The Cheshire West and Chester wards of: Chester Villages (part), Davenham & Moulton (part), Farndon (part), Gowy (part), Malpas, Tarporley, Tarvin & Kelsall, Tattenhall, Weaver & Cuddington (part), Winsford Over & Verdin (part), Winford Swanlow & Dene, and Winsford Wharton, and the Cheshire East wards of Audlem, Brereton Rural (part), Bunbury, Leighton (part), and Wybunbury.
2019–present: Following a further local government ward boundary review in 2019, the boundaries are currently:
The Cheshire West and Chester wards of Christleton & Huntington (part), Davenham, Moulton & Kingsmead (part), Farndon (part), Gowy Rural (part), Malpas, Sandstone (part), Tarporley, Tarvin & Kelsall, Tattenhall, Weaver & Cuddington (part), Winsford Dene, Winsford Gravel, Winsford Over & Verdin (part), Winford Swanlow, and Winsford Wharton, and the Cheshire East wards of Audlem, Brereton Rural (part), Bunbury, Leighton (part), and Wybunbury.
Political history (current constituency)
Since the constituency was re-established in 1983, it had always been held by a Conservative, until September 2019.
The closest the Labour Party has come to winning the seat was in the 1997 general election, when the Conservative majority was reduced to just 1,185. Eddisbury consists of mainly rural villages and small towns which are favourable to the Conservative party; Labour's only strength is in the constituency's largest town, Winsford, which currently has the seat's only local councillors. Labour fell from second to third place in the 2010 general election—the Conservative candidate held the seat with a majority of over 13,000 and a Liberal Democrat moved into second place. The 2015 election saw Labour move back into second place, and the Conservative majority fell by 1.8%.
Another general election was required to take place before the end of 1940. The political parties had been making preparations for an election to take place from 1939 and by the end of this year, the following candidates had been selected;
