Shamima Begum was smuggled into Syria by a spy working for Canada before UK authorities helped cover up the scandal, according to claims made in a new book.
Begum travelled to Syria via Turkey in 2015 along with schoolfriends Amira Abase and Kadiza Sultana in order to join ISIS.
Begum was later tracked down to a refugee camp in 2019 and stripped of her British citizenship after speaking of her desire to return to the UK.
