OK, asssuming that we've gotten past the OPs *confusion* over the differences between the free sheets and The Londoner...
The Standard is (now) primarily read by train commuters as opposed to those who live in the central 8 boroughs. Boris got elected on the back of places like Bromley voting for him. Those people are sub-Standard readers. The sub-Standard ran possibly the most partisan pre-election reporting and editorialising seen in UK papers (including The Sun in 1993). It's not that hard to make a correlation between the two unless you're astonishingly thick, like the OP.
The sub-Standard has long set the news agenda in London - the stories it covers are what Londoners (well, suburban Londoners anyway) talk about. It's the local newspaper for the capital (altho 'newspaper' is now stretching the term IMO - it's been going downhill since Hastings left and DMGT set up their integrated newsroom system, which is why you see the same stories, often with minimal or no changes to the text, in the Hate, Metro, Standard AND London Lite).#
Altho this debate would be easier if some of the posters on here had even half a clue about newspaper publishing generally, and DMGT in particular...
