Generally, the BCE is thinking along the correct lines for this area, although there is no need to put Camden wards into a Holborn & St Pancras seat, and their initial proposal for that seat does not actually contain Holborn. As for Central London, although an argument could be made for having the entire Royal Borough of Kensington & Chelsea into one seat, the connections between it and Hammersmith & Fulham/Westminster tell a different story. I also believe that Hornsey & Wood Green should remain intact (one of a handful of Greater London constituencies that can be left intact), and that it is Tottenham which should expand upwards into the outer reaches of Edmonton. Also, a Finchley & Southgate seat should actually contain all of Finchley even if for quota reasons it cannot contain all of Southgate. Mill Hill should stay connected with Hendon, not with Barnet/East Barnet.
My alternative 2018 Review constituencies for North and Central London look like this:
Hammersmith & Fulham succeeds Hammersmith.
Kensington & White City succeeds Kensington.
City of London, Westminster & Chelsea succeeds Cities of London & Westminster
Paddington & Marylebone succeeds Westminster North.
Hampstead & Golders Green succeeds Hampstead & Kilburn.
Finchley & Southgate succeeds Finchley & Golders Green.
Enfield East succeeds Edmonton.
Enfield West succeeds Enfield North.
Hornsey & Wood Green is unchanged from its 2010 boundaries.
I will be taking a short break from this series with the Witney by-election coming up this week. But after this short break will come my alternative constituencies for North West London (Ealing, Hounslow, Hillingdon, Harrow and Brent).
