Boris Johnson has insisted that his tenure as London mayor will not be used to test Conservative policies.
The mayor told the FT on Tuesday that his administration would not act as a "Petri dish" for the Tories ahead of a general election.
"I know that there is a huge appetite for read-across and everybody wants to see me as the advance guard," he said.
"London is meant to be the Petri dish into which Tory central office is introducing the bacillus of their policies, [but] it's not like that at all."
"We are developing a lot of new things [and] I hope they are broadly congruent with things that Conservatives might like to do when they get into office."
In an interview to mark his first 100 days in office, Johnson also dismissed problems he has experienced.
These include the resignation of two aides, among them his deputy Ray Lewis, who was accused of sexual and financial misconduct, and wrongly claiming to be a justice of the peace.
"To a certain extent I think it would have been a dramaturgical cheat not to have had some sort of thing about which people could make exactly the point [about incompetence]," he told the paper.
"It would have been a fraud on the electorate not to produce something and there will be things like that, of course."
The mayor also acknowledged that it would take some work to ensure a legacy for the 2012 Olympic Games.
He said: "I think there are things to be done on the venues still and I haven't lifted my reserve on that. There are also, I think, serious questions to be asked about the legacy value of some of the sites and some of the venues.
"I want to make sure that we have lasting value from these sites... [and] I want to make sure that we can alchemise them into gold for London for 50 years to come, and that is going to take some pretty crunchy work."
