We got a better deal out of it than some parts of the UK. The Boundary Commission is proposing that Salford and Manchester become a seat. That is a controversial decision and George Osborne loses his seat.

While the new Dulwich and Sydenham seat crosses borough boundaries, it's more locally focused than the current seats of Lewisham West and Penge (the latter goes back to Beckenham) and Dulwich and West Norwood. (The Lambeth side goes to a new Brixton seat)
