History of constituencies and boundaries[edit]

Prior to 1832[edit]

Since 1295, the Parliamentary County of Buckinghamshire 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 six Parliamentary Boroughs, namely Amersham, Aylesbury, Buckingham, Chipping Wycombe, Great Marlow and Wendover, all returning 2 MPs each.

1832-1885[edit]

The Great Reform Act of 1832 radically changed the representation of the House of Commons, with the County's representation being increased to 3 MPs and the Boroughs of Amersham and Wendover abolished. Unusually, the contents of the Parliamentary Borough of Aylesbury were defined within the Act itself to include the "Three Hundreds of Aylesbury", which extended the seat to include Wendover and Princes Risborough.[4]

Under the Reform Act of 1867, the representation of the Boroughs of Buckingham, Chipping Wycombe and Great Marlow were reduced to 1 MP.

1885-1918[edit]

Under the Redistribution of Seats Act 1885, the County was divided into 3 single-member constituencies, namely the Northern or Buckingham Division, the Mid or Aylesbury Division and the Southern or Wycombe Division. The remaining Parliamentary Boroughs were all abolished and absorbed into the County Divisions which took their names, with Great Marlow being absorbed into the Wycombe Division, which also included Beaconsfield and Slough.

The table shows an approximate representation of the development of constituencies in Buckinghamshire 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)

1918-1945[edit]

Under the Representation of the People Act 1918, the three County Divisions were retained, with altered boundaries: north-eastern parts of Aylesbury, including Linslade and Wing were transferred to Buckingham; Beaconsfield and Amersham were transferred from Wycombe to Aylesbury; and Wycombe gained Eton from the abolished Parliamentary Borough of New Windsor in Berkshire.

1945-1950[edit]

The House of Commons (Redistribution of Seats) Act 1944 set up Boundaries Commissions to carry out periodic reviews of the distribution of parliamentary constituencies. It also authorised an initial review to subdivide abnormally large constituencies in time for the 1945 general election. This was implemented by the Redistribution of Seats Order 1945 under which Buckinghamshire was allocated an additional seat. As a consequence, the new County Constituency of Eton and Slough was formed from the Wycombe constituency, comprising the Municipal Borough of Slough, the Urban District of Eton and the parishes to the south of Beaconsfield making up the Rural District of Eton. To compensate partly for the loss of these areas, the parts of the Rural District of Wycombe not in the constituency thereof, which included Princes Risborough and Hughenden, were transferred from Aylesbury.

1950-1974[edit]

The Representation of the People Act 1948 increased the county's representation once again, from 4 to 5 MPs, with the creation of the County Constituency of South Buckinghamshire. This comprised Beaconsfield, Amersham and the Chalfonts, transferred from Aylesbury, and the Rural District of Eton, transferred from Eton and Slough (which was redesignated as a Borough Constituency). There were no changes for the 1950 general election under the First Periodic Review of Westminster Constituencies.

1974-1983[edit]

Under the Second Periodic Review, representation was increased to 6 MPs with the formation of the new County Constituencies of Beaconsfield and Chesham and Amersham, which largely replaced the abolished South Buckinghamshire constituency. Beaconsfield comprised the Urban District of Beaconsfield and the Rural District of Eton, while Chesham and Amersham combined Amersham and the Chalfonts with Chesham and the remaining, northern part of the Rural District of Amersham, transferred from Aylesbury. The northern parts of the Rural District of Wycombe, including Princes Risborough (but not Hughenden) were transferred back from Wycombe to Aylesbury. Buckingham lost Linslade which had been transferred to Bedfordshire on its amalgamation with the neighbouring Urban District of Leighton Buzzard and was now included in the constituency of South Bedfordshire.

1983-1992[edit]

The Third Review reflected the changes to the county of Buckinghamshire arising from the Local Government Act 1972, resulting in Eton, Slough and some surrounding areas being transferred to Berkshire. The constituency of Eton and Slough was abolished with the area constituting the Borough of Slough forming the new Borough Constituency of Slough, and the small Urban District of Eton which was absorbed into the Royal Borough of Windsor and Maidenhead being included in the County Constituency of Windsor and Maidenhead. The parishes of the Rural District of Eton also transferred to Berkshire, which included Datchet, were transferred from Beaconsfield and included in the new County Constituency of East Berkshire.

In the north of the county, the new County Constituency of Milton Keynes was formed from parts of the Buckingham constituency. This reflected the growth of the new town of Milton Keynes since its foundation in 1967. The new constituency comprised the Borough of Milton Keynes, with the exception of Stony Stratford and Wolverton, which were retained in Buckingham. In turn, Buckingham gained north-western parts of the Aylesbury constituency.

Elsewhere, Great Missenden was transferred from Chesham and Amersham to Aylesbury, Hazlemere from Wycombe to Chesham and Amersham and areas to the east of High Wycombe from Wycombe to Beaconsfield.

1992-1997[edit]

Uniquely outside the normal cycle of periodic reviews by the Boundaries Commission, the constituency of Milton Keynes, due to its rapid growth, was split into two separate constituencies for the 1992 general election: the County Constituency of North East Milton Keynes and the Borough Constituency of Milton Keynes South West. Stony Stratford and Wolverton were transferred from Buckingham and included in Milton Keynes South West.[5]

1997-2010[edit]

The Fourth Review saw only minor changes to the Buckinghamshire constituencies, included the transfer of the District of Aylesbury Vale ward of Aston Clinton from Aylesbury to Buckingham.

2010-present[edit]

In the Fifth Review the Boundary Commission for England proposed changes to realign constituency boundaries with the boundaries of current local government wards, and to reduce the electoral disparity between constituencies. The changes included the return of Great Missenden to Chesham and Amersham, Hazlemere to Wycombe and Aston Clinton to Buckingham. In addition, Marlow was transferred from Wycombe to Beaconsfield and Princes Risborough from Aylesbury to Buckingham. The boundary between the two Milton Keynes constituencies was realigned and they were renamed as Milton Keynes North and Milton Keynes South.

Changes proposed for 2022[edit]

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 meet these requirements, the Commission was able to treat Buckinghamshire (including the unitary authority of Milton Keynes) as a sub-region of the South East Region and recommended that the county retained seven seats, one of which (Beaconsfield) was unchanged. The constituency of Aylesbury would be moved northwards, gaining south-eastern parts of Buckingham, including Wing. South-eastern areas, including Stokenchurch, would be transferred to Wycombe and south-western areas, including Greater Hughenden, to Chesham and Amersham.[6]

It was proposed that Buckingham regain the parts of the Borough of Milton Keynes it had lost in 1992 - Wolverton from Milton Keynes North and Stony Stratford from Milton Keynes South and, consequently, be renamed Buckingham and Milton Keynes West. The boundary between the two Milton Keynes constituencies would be realigned once again, with Bradwell and Stantonbury being transferred from North to South, and south-eastern parts of the Borough moving in the opposite direction. Milton Keynes North would be renamed Milton Keynes North East.[6]
