The British military viewed Harry's confession as exploitation of his military career for financial gain as well as playing right into Iran's propaganda.
In a report, Prime Minister Rishi Sunak described Mr Akbari's hanging, after being accused of being an MI6 spy, as a 'callous and cowardly act, carried out by a barbaric regime'.
Iran's foreign ministry responded by tweeting out: 'The British regime, whose Royal Family member sees the killing of 25 people innocent people as the removal of chess pieces and has no regrets over the issue, and those who turn a blind eye to a war crime, are in no position to preach to others on human rights.'
