The Elizabeth Line, being delivered by Crossrail Ltd, was due to be opened December 2018. However, at the end of August 2018 it was announced that the launch of the new line will be delayed until Autumn 2019.

Below are a list of correspondences between the Transport Committee, the Mayor and the Financial Conduct Authority.
