It is, frankly, an obvious lie. The tipping point wards in RBKC have a higher proportion of baronets than they do of social housing.
The Kensington constituency doesn't include Chelsea, which is very safely Conservative. North Kensington is very strong for Labour and there are a few other pockets of support scattered about, but Chelsea and South Kensington are incredibly wealthy and their electorates are rock-solid Conservative under any conceivable circumstances.
And, actually, if the Kensington constituency was its own council a Labour majority would still be a massive, massive longshot due to the spread of support in the seat.
