The Duchess of York spoke of the struggles her daughters faced at school as she launched a new charity education initiative.
Sarah Ferguson, 59, told how Princess Beatrice, 30, needed extra support in the classroom because of her dyslexia.
The mother-of-two explained that while Beatrice and Eugenie, 28, were able to thrive at school, not all children are given the same opportunity.

‘Eugenie, as you now know, is disabled with 12in metal rods down her back,’ the Duchess of York said in a new interview.
‘Beatrice is dyslexic with special needs at school. And yet they had an education, so why isn’t any other child allowed that same luxury? And why is it a luxury?’
Princesses Beatrice and Eugenie both attended Upton House School in Windsor before moving onto Coworth Park School to finish their primary education.
Both girls later attended St George’s School, Ascot, with Eugenie later boarding at Malborough College in Wiltshire.
The Duchess of York spoke as she launched a fundraising campaign for her charity Street Child, of which Beatrice and Eugenie are both global ambassadors.
Street Child was among the charities represented at the wedding of Princess Eugenie and Jack Brooksbank at Windsor Castle last month.

Hands-on approach: The Duchess of York on the ground in Janakpur, Nepal. She shared this photo on announcing she had merged her charity Children in Crisis with Street Child in July
The Count Me In appeal will use funds to buy school uniforms, train teachers and build classrooms for disadvantaged youngsters in 10 countries from Sierra Leone to Afghanistan.
The duchess said: ‘There are 121 million children who don’t go to school. They not only don’t go to school but they don’t have the opportunity to go to school … and that statistic has to change.’
The charity explained a £15 donation is enough to cover a child’s school fees, while £300 is enough to pay for the training of one teacher.
The UK Government has pledged to match all public donations to the Street Child Count Me In campaign made before 21 February 2019.
All Government funds will be put towards the organisation’s efforts in Sierra Leone.

Street Child was formed by a merger of an organisation of the same name founded by Tom Dannatt, son of former British Army head Lord Dannatt, and Sarah’s Children in Crisis organisation.
Sarah recently travelled to Nepal where Street Child works to learn about the challenges children face in the country.
The duchess, Street Child’s founder patron, said: ‘What I saw was in fact massive hope from the children because someone was listening and yet they had nothing.’
She described how she met a young girl called Ruby who wanted a school for her community so she could be educated and one day become a teacher.
Sarah added: ‘If we don’t build a school for Ruby in two years’ time she will have to get married at the age of 12 in order to sustain herself in the local area because of tribe rules.
‘If we can get a school so she can get her dream to be a teacher, imagine that story.
‘Those children were fantastic, all they wanted was a chance and surely Street Child can give them that chance.’
