At least 347 people have now been put to death this year, according to the UK-based campaign group Reprieve.

“It almost seems that it doesn’t matter to them who they execute, as long as they send a message to society that there’s a zero-tolerance policy on whatever issue they’re talking about - whether it’s protests, freedom of expression, or drugs,” said Ms Basyouni.

The de facto ruler of Saudi Arabia, Mohammed bin Salman - who became crown prince in 2017 - has changed the country profoundly over the past few years, loosening social restrictions while simultaneously silencing criticism.

In a bid to diversify its economy away from oil, he has opened Saudi Arabia up to the outside world, taken the religious police off the streets, and allowed women to drive.

But the kingdom’s human rights record remains “abysmal”, according to the US-based campaign group Human Rights Watch, with the high level of executions a major concern. In recent years, only China and Iran have put more people to death, according to human rights activists.
