Could Princess Charlotte be one of the first girls ever to attend Eton?

Princess Charlotte could make history as one of the first ever girls to attend Eton College if the school goes co-ed.

Prince George, nine, was reportedly spotted last week checking out the boarding school where he could soon become a student, along with his parents Prince William and Princess Kate, both 41.

Sources close to the couple have previously said they don’t want their children to attend segregated schools – indicating eight-year-old Charlotte might be able to follow in her big brother’s footsteps if the school decides to admit girls within five years.

Although the school only takes pupils from the age of 13 (Year 9), students wishing to attend the £45,000-a-year school which has trained 20 Prime Ministers must be registered by the time they finish Year 5 (Age 10).

It comes after word got out that the Berkshire boarding school would consider girls to join for the first time in its 600-year history.

Eton’s Provost Lord (William) Waldegrave, told the Daily Mail’s Richard Kay last year that the school will become ‘co-ed in due course’.

‘Each year the governors of Eton consider whether Eton should become a student.

And we’re not quite there. But eventually we will of course go co-ed.’

Lord Waldegrave, 77, is the brother of Lady Susan Hussey, right-hand man to the late Queen Elizabeth, and has served as Provost or Chair of Eton’s governing body since 2009.

However, the former Tory grandee will soon be stepping down after 14 years as Provost – or Chairman of the Governors.

By the time Prince George arrives, a new man – or possibly a woman – will be in the post.

Lord Waldegrave made the remarks at a reunion dinner at Eton for those who left in 1983.

Intriguingly, this included a small group of ‘Old Etoniennes’ – about 16 women who attended the school for just one semester, during which they prepared for the exam which was then taken by anyone hoping to enter the universities of Oxford or Cambridge.

Prince William and his younger brother, Prince Harry, 38, were both high school students at Eton College, where William enrolled in 1995.

Currently, Eton College lists tuition fees as £15,432 per half – where ‘half’ means ‘term’ and three terms in the school year.

This works out to £46,296 a year for tuition fees at the prestigious school, whose alumni include David Cameron, Boris Johnson and George Osborne.

After moving to Windsor last year, the Welsh children all attend Lambrook Primary School in Berkshire, just ten minutes’ drive from their new home, Adelaide Cottage.

Lambrook boasts ‘first-class teaching and excellent facilities’, including a 25-metre swimming pool, nine-hole golf course, artificial turf, clay courts, squash court, cricket and other sports fields.

The fees cost £4,389 per semester for Year 2 pupils such as Louis, £6,448 per semester for Years 3-4 such as Charlotte, and £6,999 per semester for George through Years 5-8, with an additional £ 1,481 per semester for boarding for Y3-8.

Famous alumni include the actor Alex Pettyfer, the sons of wartime Prime Minister Herbert Asquith, and entrepreneur Giles Clarke, who founded Majestic Wine.

Prior to the move, Prince George and his little sister, Princess Charlotte, eight, attended Thomas’s preparatory school on Battersea High Street.

William is said to be ‘popular and happy’ at Eton, while the pair have recently moved to Windsor Castle, which is nearby, which would allow George to travel back at weekends.
