It is disappointing to read the reply from DfT (post #942). In particular, when replying to the question on the loss of evening Charing Cross services they claim that:

Probably their spokesman does not even realise that the ELL will only have 4tph after 10.15pm, with oddly spaced gaps, making it a very poor option for travelling home from an evening in the West End.

Also, the Jubilee line is hardly close to most of the West End, necessitating either a long walk to a Jubilee Line station, or a long walk to change tube line at Waterloo.

I would be keen to see the FH Soc focus on this lack of evening ELL services when next lobbying DfT, TfL, MPs, etc. I will be writing to London Travel Watch, and my MP again once I know who it is.
