The statement made by Stephen Greenhalgh is absurd. If he didn't do anything wrong why did he apologise? It looks like something did happen and Boris Johnson needs to get to the root of this immediately.
It is completely unacceptable that someone in such a senior position cannot recollect whether such a serious incident occurred only a few weeks ago.
Regardless of whether a formal complaint is made or not this needs investigating. This is a serious matter that needs urgent clarification. If it remains unclear or unresolved then he should step down.
I understand that this has been going on for four weeks, we need to know who knew what and when in the Mayor's Office, Boris needs to establish what has been going on.
