TfL fares to rise or not?

Ken Livingstone promised in October 2007 that:

""The funding package for Crossrail does not require a fare increase.

"It is the fares generated by Crossrail that do that."

However the BBC report:

"But in emails seen by the BBC, the fare rises were included in Transport for London's (TfL) business plan, which had been signed off by the mayor.

Mr Livingstone explained that TfL wanted the price rises but that he reconsidered and revised the plan."

I wonder what the truth is.
