History of constituencies and boundaries

Prior to 1832

Since 1295, the Parliamentary County of Berkshire, along with all other English Counties regardless of size or population, had elected 2 MPs to the House of Commons in accordance with the freehold property franchise. The county also included the Parliamentary Boroughs of Reading, Wallingford and New Windsor each returning 2 MPs and Abingdon (which was partly in Oxfordshire) which returned 1 MP (one of only a handful of English Boroughs to do so).


The Great Reform Act of 1832 radically changed the representation of the House of Commons. The County's representation was increased to 3 MPs, whilst that of the Borough of Wallingford was reduced to 1 MP. Under the Reform Act of 1867, the representation of the Borough of New Windsor was also reduced to 1 MP, at the same time expanding its boundaries to include Clewer and Eton (the latter being north of the River Thames in Buckinghamshire).[5]


Under the Redistribution of Seats Act 1885, the County was divided into 3 single-member constituencies, namely the Northern or Abingdon Division, the Southern or Newbury Division and the Eastern or Wokingham Division. The Boroughs of Wallingford and Abingdon were abolished and absorbed into the county Division of Abingdon and Reading had its representation reduced to 1 MP.

The table shows an approximate representation of the development of constituencies in Berkshire since 1885. The text below gives a more detailed description.

BC = Borough Constituency (prior to 1950 - Parliamentary Borough or Division thereof)

CC = County Constituency (prior to 1950 - Parliamentary County of Division thereof)


Under the Representation of the People Act 1918, the Parliamentary Borough of New Windsor and the county Division of Wokingham were abolished and replaced by the county Division of Windsor, which also included Maidenhead. Eton was now included in the Wycombe Division of Buckinghamshire The Municipal Borough of Wokingham itself was added to the Newbury Division and the Parliamentary Borough of Reading was expanded in line with the County Borough, including the absorption of Caversham, to the north of the River Thames, which had previously been part of the Henley Division of Oxfordshire.


The Representation of the People Act 1948 increased the county's representation from 4 to 6 MPs. Reading was split into the two Borough Constituencies of Reading North and Reading South and Wokingham was re-established as a County Constituency, comprising the borough of Wokingham and rural areas to the south and east of Reading, transferred from Newbury, and extending eastwards to include the Rural District of Easthampstead (which incorporated Bracknell), transferred from Windsor.


Under the First Periodic Review of Westminster Constituencies Reading North and Reading South were recombined, with one ward of the County Borough being included in each of the Newbury and Wokingham constituencies.


Under the Second Periodic Review, representation was increased back up to 6 MPs with the recreation of Reading North and Reading South. The County Borough wards in Newbury and Wokingham were returned whilst Reading South (which was designated as a County Constituency) was extended southwards to include parts of the Rural District of Wokingham, transferred from the constituency thereof.


The Third Review reflected the changes to the county of Berkshire resulting from the Local Government Act 1972 and saw major changes. The bulk of the area comprising the constituency of Abingdon had been moved to Oxfordshire, with the majority of its contents, including Wantage, Wallingford, Didcot and Faringdon being included in the new County Constituency of Wantage. The town of Abingdon-on-Thames itself, together with areas to the west of Oxford, was included in the new County Constituency of Oxford West and Abingdon. The small part which was retained in Berkshire was transferred to Newbury. The county had absorbed the Municipal Borough of Slough and the small Urban District of Eton (which together had formed the Borough Constituency of Eton and Slough) from Buckinghamshire. Slough was formed as a new Borough Constituency and Eton was added back to Windsor.

A further County Constituency of East Berkshire was created, largely comprising the Borough of Bracknell (formerly the Rural District of Easthampstead) but also including the areas comprising the former Rural District of Windsor (including Old Windsor and Sunningdale), transferred from Windsor and Maidenhead, and the parts of the former Rural District of Eton (including Datchet) which had also been transferred from Buckinghamshire to Berkshire and were previously part of the County Constituency of Beaconsfield.

Reading North and Reading South were abolished once again and replaced by the County Constituencies of Reading East and Reading West. Reading East was formed largely from parts of Reading South, together with parts of Reading North, including Caversham. Reading West was formed largely from parts of Reading North and extended westwards to include parts of Newbury. North-western parts of Reading South were transferred back to Wokingham.


The Fourth Review resulted in a further increase from 7 to 8 MPs with the abolition of Windsor and Maidenhead and the creation of the two separate County Constituencies of Maidenhead and Windsor. Maidenhead included Bisham and Cookham and was extended westwards to include northern parts of Wokingham. Windsor included Bray, Eton and the Slough ward of Foxborough. It was extended southwards to include parts of East Berkshire (Datchet, Old Windsor, Sunningdale and Ascot). East Berkshire was abolished with remaining parts forming the basis of the new County Constituency of Bracknell, which also included the ward of Wokingham Without, transferred from Wokingham, and Finchampstead, transferred from Reading East.

Reading East was redesignated as a Borough Constituency, gaining parts to the east of the borough from Wokingham in exchange for areas to the south, including Shinfield. Wokingham also added two wards from Newbury. Finally, Reading East gained the borough ward of Katesgrove from Reading West in exchange for the ward of Whitley.


Fifth Review - Modest changes, including the transfer of Bray from Windsor to Maidenhead, Binfield from Bracknell to Windsor and the return of Foxborough ward from Windsor to Slough. Further marginal changes due to revision of local authority wards.

Changes proposed for 2022

The Boundary Commission for England submitted their final proposals in respect of the Sixth Periodic Review of Westminster Constituencies (the 2018 review) in September 2018. If these proposals are approved by Parliament they will come into effect at the next UK general election which is due to take place in May 2022 under the terms of the Fixed-term Parliaments Act 2011.

Under the terms of the Parliamentary Voting System and Constituencies Act 2011, the Sixth Review was based on reducing the total number of MPs from 650 to 600 and a strict electoral parity requirement that the electorate of all constituencies should be within a range of 5% either side of the electoral quota. The review was carried out using the official UK electorate figures for 2015 and the electoral quota was set at 74,769, establishing a range of 71,031 to 78,507.[6]

In order to minimise the changes required, the Commission recommended combining Berkshire with Surrey as a sub-region of the South East Region. However, this involved only one ward (Windlesham in the Borough of Surrey Heath in Surrey) being transferred from the constituency of Surrey Heath to the constituency of Windsor. After adjusting for this, the Commission recommended that Berkshire retained eight seats, with no name changes, of which four (Bracknell, Maidenhead, Slough and Wokingham) were unchanged. Elsewhere, Reading West would gain a further two District of West Berkshire wards (Basildon and Bucklebury) from Newbury and the Borough of Reading ward of Battle would be transferred from Reading West to Reading East.[6]
