I'd think that it would /will be impossible to have him removed from office due to the fact that the voting populace of London is by far predominatly non indigenous now. Another person who dislikes the UK culture and people will follow him , probably more abhorrent than Khan.
This is a classic example of the shift that occurs when the balance is tipped in favour of that particular group or ethnicity , the power now lies with them and they can create the enviorment that they wish to the detrement of those that they now hold in contempt.
Unfortunately their values and social practices destroy all that we hold dear .
London has long ceased to be reflective of the UK and has sunk into a sad shadow of it's former self .My wife was born in London and we spent time going back there almost weekly in the mid to late 90's when we lived in Beds. There was a sea change occuring then but that world is all but gone now.
Other cities will follow, and soon.
I've recently watched some Youtube footage of life in London ,and UK as a whole, from the 60's /70's and even 80's and the change is quite astonishing and quite sad .
It makes me laugh when the featured couples on Escape to the Country programmes say that they wish to escape the cities " because it's so much busier " than years before ........Mmmm

And yeah , he's and obnoxious little man who deflects and avoids answering any questions that expose the deceit ,degeneration, danger and islamification of all that he now truly Lords over ......
