Nobel laureate Malala Yousafzai and her family have now become millionaires from the girl’s international best-selling book and lecture tours, says a new report.

A firm set up to handle cash said Malala has £2.3million in its coffers.

Last year the company turned over £1.1million, and the teenager will have to pay a tax bill of £200,000.

Salarzai Limited – registered in London –runs with the help of Malala’s father, Zia.

Accounts submitted to Companies House reveal the principal activity of the firm is “owning the rights to the story” of Malala.

She came to prominence when a Taliban gunman shot her in the head on her school bus in 2012, Malala continued campaigning on the world stage and in 2014 became the youngest Nobel Peace Prize winner.

Now 18, she lives in Britain but devotes much of her time and energy to the cause of education for Syrian refugee children. An accomplished public speaker who brought a United Nations audience to its feet in a celebrated speech in 2013, she hopes to make a powerful impact at the London event.

Her, book, ‘I Am Malala: The Story of the Girl Who Stood Up for Education and was Shot by the Taliban’, was published in 2013.

Malala stars in speaking engagements, and has become an advocate for women’s rights, across the world.

In a recent interview, she had said she was working hard on improving her English so she could complete her schooling in Britain and go to university, but also wanted to dedicate herself with “my sister” Malala to the cause of education for fellow Syrian refugees.

She has also set up a drive to try and help the 60 million girls in the world who do not have access to education.

Malala’s Fund aims to “raise girls’ voices and ensure every girl has access to 12 years of free, safe, quality primary and secondary education”.
