Crossrail boss Sir Terry Morgan today challenged London’s mayor over his version of events leading up to the line’s postponed opening.
Sadiq Khan has repeatedly said he only learned of the delayed launch in August but Sir Terry says he told the mayor a month earlier.
The £15bn east-west rail link was due to open next Sunday but unfinished stations and signalling problems have put back the launch until next Autumn.
The project needed a £650m government bailout in July and a further £300m last month. The final bill is expected to rise.
