The proportion scoring worse than a good ranking rose from 31 per cent to 40 per cent in the last year, Ofsted will reveal in its annual report on Wednesday.

The regulator of UK classrooms said: “A number are highly conservative Christian, Jewish, or Muslim faith schools.

In the annual report, the Chief Inspector of Schools is also expected to reveal that 90 per cent of all primary schools and nearly 80 per cent of all secondary schools are now rated either good or outstanding.

“It’s not good for our children to be highly sexualised.”

Philip Schofield said he found the conversation “utterly abhorrent” and finished the segment by stating the show would be returning to 2017 rather than “medieval Britain”.

Commenting on the interview Mrs Williams said Phillip Schofield was “on the offensive” during the interview and his behaviour was “very…
