A science teacher from rural Kenya, who gives away most of his salary to support poorer pupils, has won a $1m prize (£760,000) for the world's best teacher.

Peter Tabichi, a member of the Franciscan religious order, won the 2019 Global Teacher Prize.

Brother Peter has been praised for his achievements in a deprived school with crowded classes and few text books.

One of the ten contenders for the award was a teacher from Georgia, Vladimer Apkhazava.
