Nobel Laureate Malala Yousafzai and her family have become millionaires as a result of income from her memoir describing life under Taliban rule in Pakistan's picturesque Swat valley and appearances on the lecture circuit around the world.

The 18-year-old Pakistani teenager who survived a shot to the head by the Taliban had relived the incident and her life in the Swat Valley in 'I am Malala', co-written with 'Sunday Times' journalist Christina Lamb.

A company set up to protect the rights to her life story had 2.2 million pounds in the bank by August 2015 and made a pre-tax profit of 1.1 million pounds.

Malala, her father Ziauddin Yousafzai, and her mother Toor Pekai are joint shareholders of the company, Salarzai Ltd, 'The Times' reports. They are now based in Birmingham, where Malala '" who became the youngest recipient of the Nobel Peace Prize in 2014 - attends Edgbaston High School for Girls.

Her autobiography, which documents her experiences growing up in Pakistan's Swat Valley under Taliban rule and being shot while travelling home from school on the bus with her friends, was published in October 2013 by Weidenfeld & Nicolson in the UK in a deal reported to be worth about 2 million pounds.
