What Mr Khan really wants to tackle in Bromley, however, is transport, and has been vocal about introducing a four-year fare freeze on TfL services across London.
With no tube network in the borough, there has long been a suggestion that Bromley is somewhat isolated from the rest of the city, and while Mr Khan hasnt ruled out the possibility of extending the underground to the south-east, he says there are other ways he wants to help residents in getting around the capital.
He said: Extending tube services on the Bakerloo line is an option, and something we want to look into, but its important to improve on the transport thats already available.
If I use the tube, I can change as many times as I want until I get to my destination, but if I have to take two or three buses I get charged each time.
So I want to introduce The Hopper, which would allow Bromley residents to hop on an unlimited number of buses for a 60 minute period, and provide excellent value for money.
Weve heard a lot about Crossrail, which connects the east and west, and Crossrail 2 to connect the north and south but what about a Crossrail 3 to serve suburban areas like Bromley?
I think that would be beneficial and I have called on the chancellor to recognise this.
With rail firm Southeastern so often in the line of criticism, Mr Khan is united with his Tory opposite number in wanting Transport for London (TfL) to take over services in the borough.
