A final decision will come in autumn next year on details of the new Lewes and Uckfield Parliamentary constituency.
Proposals from the Boundary Commission are to establish a whole new constituency, which would also include Hailsham, but not Crowborough.
At present the three towns are part of the Wealden Constituency, represented by Conservative Nus Ghani.
Lewes is in a separate constituency, represented by Tory Maria Caulfield, and takes in an area to the south of the county town.
The changes are part of a redrawing of boundaries to try and ensure an equal number of voters between each English Parliamentary seat.
The proposals do not affect town, district or county council wards.
Wealden District Council is asking the Boundary Commission to change the name of the new constituency to Hailsham, Lewes and Uckfield.
The suggested boundaries would put neighbouring villages of Maresfield, Buxted and Framfield in a new Crowborough and Tunbridge Wells constituency.
Wealden District Council would like to see Maresfield and Buxted remain within the the new Lewes – Uckfield constituency.
Final proposals are due in September next year, after the latest round of consultation closed earlier this month.
