From he BBC Link: "The National Foundation for Educational Research (NFER) report found teachers in the most deprived schools were more than three times as likely (53%) to say their pupils were at least four months behind, compared with those in the wealthiest schools (15%)."
From the actual Report:

A survey by the Sutton Trust (2020) found that pupils in
independent schools were significantly more likely than
those in state schools (especially the most deprived
state schools) to be receiving high-quality interactive
remote learning. Well-cited explanations include that
pupils in state schools were less likely to have internet
connectivity and digital devices and/or adequate study
space in the home than independent school pupils,
making this form of learning challenging; and that state
schools were less likely to have well-developed learning
platforms for the setting and submission of work."
-- That from just a cursory look at it.
