At the London Assembly’s Transport Committee last weekk, the long-running row over who said what and when over the delay to the Crossrail project saw Transport for London (TfL) caught in the crossfire with accusations of a pre-meditated cover-up.

Sir Terry Morgan, who was forcibly resigned last month as non-executive chair of Crossrail Ltd, accused TfL of editing his weekly briefing notes to mayor Sadiq Khan and giving him a script with which to conceal the expected delay from a public meeting of the TfL board. 

He also claimed that officials at the transport authority then engaged in an ‘offline’ discussion to plan a communications strategy during between late July and late August 2018 – the time when Mr Khan claims not to have known that the project would be delayed.
