Some briefing that London will be a relatively safe Labour win rather than the blowout landslide that some predicted
One factor mentioned which may actually be relevant, rather than merely customary pre-election expectations management, is a lot of younger people/students not actually being resident in London right now due to Covid (though you might hope pollsters made some attempt to account for that)
That might be true for graduates but its not the case for students. London has a higher share of the student population than its share of the population as a whole (16% as opposed to 14%) but is a net exporter of students. See
here for the relevant figures, in particular:
o 94,800 students domiciled in London remained in the capital, making up 59% of First degree undergraduates;
o 65,900 students came to London from the rest England, mostly from the South East;
o 115,000 students left London to study elsewhere and 45% went to the South East or the East of England.
It makes up for this, obviously, by having a far higher proportion of foreign students.
