1885–1918 • The Sessional Divisions of Aylesbury, Chesham, and Linslade; and • Parts of the second Sessional Division of Desborough and the Sessional Division of Winslow.
1918–1945 • The Borough of Aylesbury; • The Urban Districts of Beaconsfield and Chesham; • The Rural District of Amersham; • The part of the Rural District of Aylesbury not included in the Buckingham Division; • The Rural District of Long Crendon parish of Towersey; and • The Rural District of Wycombe parishes of Bledlow, Bradenham, Ellesborough, Great and Little Hampden, Great and Little Kimble, Horsenden, Hughenden, Ilmer, Monks Risborough, Princes Risborough, Radnage, Saunderton, and Wendover.
Linslade and Wing were transferred to the Buckingham Division and Amersham and Beaconsfield were transferred from the Wycombe Division. 1945–1950 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 election. This was implemented by the Redistribution of Seats Order 1945 under which Buckinghamshire was allocated an additional seat. As a consequence, the parts of the (revised) Rural District of Wycombe in the Aylesbury Division, including Hughenden and Princes Risborough (but not Wendover which had been moved from the Rural District of Wycombe to that of Aylesbury by the reorganisation of local authorities in Buckinghamshire), were transferred to Wycombe. There were no further changes and the revised composition of the constituency, after taking account of changes to local authorities, was: • The Borough of Aylesbury; • The Urban Districts of Beaconsfield and Chesham; • The Rural District of Amersham; • Parts of the Rural Districts of Aylesbury and Wing; and • The part of the Rural District of Bullingdon in Buckinghamshire.
1950–1974 • The Borough of Aylesbury; • The Urban District of Chesham; • The Rural District of Aylesbury; and • The Rural District of Amersham parishes of Ashley Green, Chartridge, Cholesbury-cum-St Leonards, Great Missenden, Latimer, Lee, and Little Missenden.
Beaconsfield and southern parts of the Rural District of Amersham (including Amersham itself) were transferred to the new constituency of South Buckinghamshire. The boundary with Buckingham was redrawn to align with the northern boundary of the Rural District of Aylesbury. 1974–1983 • The Borough of Aylesbury; • The Rural District of Aylesbury; and • The Rural District of Wycombe parishes of Bledlow-cum-Saunderton, Bradenham, Ellesborough, Great and Little Hampden, Great and Little Kimble, Ibstone, Lacey Green, Longwick-cum-Ilmer, Princes Risborough, Radnage, and Stokenchurch.
Parts of the Rural District of Wycombe, including Princes Risborough (but excluding Hughenden), transferred back from Wycombe. Chesham and the northern part of the Rural District of Amersham included in the new constituency of Chesham and Amersham. 1983–1997 • The District of Aylesbury Vale wards of Aston Clinton, Aylesbury Central, Bedgrove, Elmhurst, Gatehouse, Grange, Mandeville, Meadowcroft, Oakfield, Southcourt, Wendover, and Weston Turville; • The District of Chiltern wards of Ballinger and South Heath, Great Missenden, and Prestwood and Heath End; and • The District of Wycombe wards of Bledlow-cum-Saunderton, Icknield, Lacey Green and Hampden, Naphill-cum-Bradenham, Princes Risborough, and Stokenchurch.
Great Missenden transferred from Chesham and Amersham. Rural areas to the north and west of the town of Aylesbury transferred to Buckingham. 1997–2010 • The District of Aylesbury Vale wards of Aylesbury Central, Bedgrove, Elmhurst, Gatehouse, Grange, Mandeville, Meadowcroft, Oakfield, Southcourt, Wendover, and Weston Turville; • The District of Chiltern wards of Ballinger and South Heath, Great Missenden, and Prestwood and Heath End; and • The District of Wycombe wards of Bledlow-cum-Saunderton, Icknield, Lacey Green and Hampden, Naphill-cum-Bradenham, Princes Risborough, and Stokenchurch.
Minor changes, including the transfer of the District of Aylesbury Vale ward of Aston Clinton to Buckingham. 2010–2024 • The District of Aylesbury Vale wards of Aston Clinton, Aylesbury Central, Bedgrove, Coldharbour, Elmhurst and Watermead, Gatehouse, Mandeville and Elm Farm, Oakfield, Quarrendon, Southcourt, Walton Court and Hawkslade, and Wendover; and • The District of Wycombe wards of Bledlow and Bradenham, Greater Hughenden, Lacey Green, Speen and the Hampdens, Stokenchurch, and Radnage.
Hughenden transferred from Wycombe. Princes Risborough transferred to Buckingham, offset by return of Aston Clinton. Great Missenden returned to Chesham and Amersham. In April 2020, the Districts of Aylesbury Vale and Wycombe, as well as those of South Bucks and Chiltern were merged into the new unitary authority of
Buckinghamshire Council. Accordingly, the contents of the constituency were: • The Buckinghamshire Council wards of Aston Clinton and Bierton (part), Aylesbury East, Aylesbury North, Aylesbury North West, Aylesbury South East, Aylesbury South West, Aylesbury West, Ridgeway East (part), Ridgeway West, Stone and Waddesdon (part), Wendover, Hatton & Stoke Mandeville, West Wycombe (part), and Wing (part). The constituency is based on the large
town of
Aylesbury and its suburbs as well as a small swathe of villages broken up by woods and cultivated land in the centre of the
Chilterns which cover most of
Buckinghamshire and parts of three other counties.
2024–present Further to the
2023 periodic review of Westminster constituencies which became effective for the
2024 general election the constituency is composed of the following: • The District of Buckinghamshire wards of: Aston Clinton & Weston Turville; Aylesbury East; Aylesbury North; Aylesbury North West; Aylesbury South East (part); Aylesbury South West; Aylesbury West; Berryfields, Buckingham Park & Watermead (part); Bierton, Kingsbrook & Wing; Ivinghoe; Quainton.
The constituency was subject to significant changes, with southern, largely rural parts, including the town of Wendover, being included in the newly created seat of Mid Buckinghamshire. To partly compensate, the boundaries were extended northwards to include the communities of Ivinghoe and Wing, together with surrounding rural areas, previously part of the abolished Buckingham constituency. ==Members of Parliament==
