Boris Johnson refused to answer any questions about his Deputy Mayor this morning, as details emerged of the investigation being launched into claims of sexual and financial misconduct.
Speaking at the launch of the competition to design a new Routemaster, Boris initially said that he would only answer questions on buses, but was eventually forced to commit to answering other questions after the launch.
But before he could be held to his promise, the Mayor was quickly ushered out of the back door leaving all other questions to Peter Hendy and his press team.
However, despite Boris's reluctance to discuss the matter, the Troll understands that an investigation will begin next Tuesday. It will be led by the current head of Barnardo's, Martin Narey.
Narey is highly respected and has great experience in dealing with such sensitive issues. However, there may be a conflict of interest, with his previous role as the Director General of the Prison service during Lewis's time as a prison governor.
There are also question about who will foot the cost of the investigation. The inquiry which is expected to last a matter of "weeks rather than months" will be run by Narey who will, I am told, be 'compensated' for his time away from Barnardo's.
What will it cover?
However, some of the most serious allegations will not be covered by the investigation.
A spokesman for the Mayor said that Narey would not be looking at the allegations of child abuse at the Eastside Academy, nor at the reasons why Newham Council withdrew funding from the project.
However, what the inquiry will concentrate on is the Church of England file, the details of which have not yet been published.
The contents of the file have been described as 'truly shocking' by those who have seen it. The Mayor's office on the other hand, insist that it's claims appear to be 'completely groundless.'
