The Boundary Commission for England is currently conducting a review of Parliamentary constituency boundaries in England on the basis of new rules. These rules involve a significant reduction in the number of constituencies in England (from 533 to 502). This means South Yorkshire will go from 14 down to 13 Parliamentary constituencies.
The public meetings on these proposals are listed on the Boundary Commission for England website. I also expect this to be where the documents outlining these and the rest of the changes to be published.
The parts of the proposals that pertain to Sheffield are as follows:
There are currently 14 constituencies in this sub-region, only four of which (Doncaster Central, Doncaster North, Don Valley, and Rother Valley) have an electorate within 5% of the electoral quota. Of the remaining constituencies, all ten have electorates that are below the 5% limit. We propose to reduce the number of constituencies to 13.
We considered whether we could leave unchanged any of the four existing constituencies that had an electorate within 5% of the electoral quota and we are able to do so in our initial proposals.
In this sub-region, our options were limited by the number of electors in each of the wards in the City of Sheffield, which ranges from 12,134 to 17,646. We noted that, if we were to avoid dividing wards between constituencies, it would be challenging to create constituencies that were either based on the existing constituencies or wholly within the City of Sheffield. Given the electoral sizes of the wards, it was inevitable that some constituencies would have to be proposed that contain part of the City of Sheffield and part of an adjacent borough (either Barnsley or Rotherham). In Doncaster, we propose no change to any of the three existing constituencies.
We propose a Barnsley West and Ecclesfield constituency that crosses the boundary between the Borough of Barnsley and the City of Sheffield. Two wards of the Borough of Barnsley (Darton West and Penistone East) are included in this constituency, together with four wards of the City of Sheffield (East Ecclesfield, Firth Park, Southey, and West Ecclesfield). We note that there are good communication links along the A61 road that connects the urban Sheffield wards with the more rural Barnsley wards in the north of the constituency. We also propose that one ward of the Borough of Barnsley (Penistone West) is included in another cross-boundary constituency called Sheffield West and Penistone, together with five wards of the City of Sheffield (Crookes, Ecclesall, Fulwood, Stannington, and Stocksbridge and Upper Don). Four of these are in the existing Sheffield, Hallam constituency.
We propose that the five remaining wards of the Borough of Rotherham form a Rotherham and Sheffield East constituency, together with two wards of the City of Sheffield (Darnall, and Shiregreen and Brightside).
As a consequence of our changes elsewhere, the remaining 17 wards of the City of Sheffield are divided between three constituencies. The Sheffield Central constituency contains five wards; the Sheffield South East and Sheffield South West constituencies each contain six wards.
