The BBC reports on Boris Johnson's inability to confirm how much the Greenwich to Newham cable car will cost the taxpayer, when pressed by Caroline Pidgeon at June's Mayor's Question Time session.
Responding to Caroline's question, the Mayor was vague:
When pressed by Liberal Democrat Caroline Pidgeon, who asked him to guarantee that all the money would be recouped from the private sector, Mr Johnson said that private funds "may well cover the total cost over time.
But he added: "Whether it will cover every penny of the set up costs I can't guarantee.
The cost "may very well be zero to the public sector, but I can't tell you what it will be yet", he told the assembly.
You can read the report - and video coverage - here on the BBC website.
Since that time, construction has begun on the cable car, but - as Mayorwatch reports - there is still no guarantee it will be ready for the 2012 Games.
As of September 2011, the costs of the cable car have now risen to £60m - and TfL is taking over part of the rail budget to pay for it. Read more here at Londonist, the News Shopper, Liberal Democrat Voice and on the BBC website.
