Malala Yousufzai said that she would not ordinarily miss a day of lessons - but made an exception for her Buckingham Palace visit:
I had to miss school because I was meeting the Queen.
It's such an honour for me to be here at Buckingham Palace. It's really an honour to meet the Queen.I also wanted to raise the issue of girls not being educated on a higher platform so that the government in each country takes action on it.We need to fight for education in the suffering countries and developing countries, but also here.
Malala Yousufzai spoke to the Queen about the importance of education when they met at Buckingham Palace.
The teenager, accompanied by her father Ziauddin, gave the Queen a copy of her book, I Am Malala, during their meeting in the palace's White Drawing Room, telling her: "It is a great honour for me to be here, and I wanted to present you with this book."
Accepting the gift, the Queen replied: "That's very kind of you," before chatting with the teenager for a few moments.
She was reduced to laughter by a comment from the Duke, who quipped that in this country, people want children to go to school to get them out of the house. Malala covered her face while in a fit of giggles at his joke.

Speaking to the BBC's Panorama programme, the 16-year-old said of the prospect:
