Islington South is proposed to grow to accomodate the Camden wards of 'Holborn and Covent Garden' and 'Kings Cross' and also swallows up the City of London to become 'City of London and Islington South'. But loses the Holloway Ward to Islington North.
The desire to make constituencies come within standard size bounds means that the old, neat arrangement of largely contiguous fit with local government boundaries is all messed up in London. Islington was considered too small for two seats, so the new seats spread across Camden, Islington and City of London boundaries. What was Holborn and St Pancras now becomes (I think) Camden and Regents Park.
These are proposed changes and will probably be debated at length. Writing this article hurridly i can't quite work out the implications. If I have misunderstood something please let me know in the comments.
My gut feel is that these changes will make it even harder for local people to relate to their MP. Someone has broken the embargo on the proposed Boundary Commission changes but these seem to be it. Here's what the Boundary Commission has to say:
44. In Islington, we noted that the electorate was too small for two constituencies and we decided to expand the existing Islington North constituency to include one ward (Holloway) from the existing Islington South and Finsbury constituency. To replace the Holloway ward, we propose to include the City of London and two Camden wards (Holborn and Covent Garden, and King’s Cross). Although the City of London has had a longstanding constituency link with wards from the City of Westminster, we noted that there are also close communication links between the City of London and the south of the Borough of Islington. We decided that the constituency should be renamed The City of London and Islington South.
45. In Camden, we noted that the existing Hampstead and Kilburn constituency, which contains wards from the boroughs of both Brent and Camden, had an electorate within 5% of the electoral quota. However, with the inclusion of the Fortune Green ward in the Finchley and Golders Green constituency, it was necessary to alter the Hampstead and Kilburn constituency. We propose that it should contain only two Brent wards (Kilburn and Queens Park) and eight wards
from Camden, including three (Gospel Oak, Highgate, and Kentish Town) from the existing Holborn and St Pancras constituency. The seven remaining Camden wards, including one (Belsize) from the existing Hampstead and Kilburn constituency, form a Camden and Regent’s Park constituency, together with four wards from the north east of Westminster.
