My understanding is that trains to and from Cannon Street will only
have two tracks available to them at London Bridge and there wouldn't
be enough capacity if trains stopped at London Bridge. Hence they'll
pass straight through instead. Whereas trains to and from Charing
Cross will have three tracks available to them which does provide
enough capacity to allow stopping.

However platforms 4-9 seem to be well on their way to completion and
so why can't trains to and from Charing Cross use platforms 7-9 and
trains to and From Cannon Street use platforms 4-6? This would mean
that Charing Cross and Cannon Street services would both have three
tracks available to them which would allow all services to stop at
London Bridge.

Thanks

Presumably because platforms 4-6 do not have any connection to Cannon
Street, only to Charing Cross or Blackfriars.
