Margaret Atwood and Bernardine Evaristo have jointly won the 2019 Booker Prize after judges flout the rules by declaring a tie.

Atwood’s The Testaments and Evaristo’s novel Girl, Woman, Other earned each author an equal share of the £50,000 prize.

Atwood, 79, is the oldest ever Booker winner, while Evaristo is the first black woman to win.
