Kirstie tweeted: “In the last 48 hours I have seen, within my own family, the inequalities with education that have been so exacerbated by Covid.
“Two kids, two schools, two very different sets of results. I saw what one school did in lockdown and what one did not.”
Kirstie did not say which of her children she was referring to, while she is also step-mother to her husband’s two children from a previous relationship.
Kirstie shares sons Bay and Oscar with husband Ben Andersen.
