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 new County Constituency of Eton and Slough was formed from the Wycombe constituency, comprising the Municipal Borough of Slough and the Urban and Rural Districts of Eton. In compensation, the parts of the (revised) Rural District of Wycombe in the Aylesbury Division, including Hughenden and Princes Risborough, were transferred to Wycombe. 1950–1974: The Municipal Borough of High Wycombe, the Urban District of Marlow, and the Rural District of Wycombe.

Northern parts of the Rural District of Wycombe, including Princes Risborough, but excluding Hughenden, transferred back to Aylesbury.
