The Taliban have threatened to target Malala again and she was given tight security for her journey to the UK on Monday.

She and two other schoolgirls were attacked as they returned home from school in Mingora in the Swat Valley almost a week earlier.

The gunman who boarded the van in which she was travelling asked for her by name before firing three shots at her.

Malala is widely known as a campaigner for girls’ education in Pakistan. In early 2009 she wrote an anonymous diary for BBC Urdu about life under the Taliban, who had banned all girls in her area from attending school.
