The Principal of Queen's College in London has accused Chancellor Rachel Reeves of damaging female equality and opportunities after her private school fees VAT hike.
Richard Tillett's letter to the Times told how one private school within an hour of the Chancellor's own constituency has been forced to accept boys to a previously girls only school from September 2026.
According to the principal, Wakefield Girls' High School is soon to start welcoming boys almost 150 years after it was founded in 1878.
Mr Tillett added that another local school, Harrogate College, had taken the same decision, while a third, Queen Margaret's School in York, is closing its doors altogether.
Writing in the Times, he said: 'All-girls' education matters, and the state does not do enough to provide it.
