Sheikh Mohammed Bin Rashid Al Maktoum, the ruler of Dubai and one of the world’s richest men, has written a furious poem denouncing treachery and betrayal after his wife, Princess Haya bint Al Hussein, the daughter of the late King of Jordan and sister of the present king, secretly fled to Europe with their son Zayed, 7, and daughter Al Jalila, 11.

Al-Maktoum, known for his poetry, wrote a furious poem titled “You Live And Die”, thought to be an attempt to condemn the princess for leaving him. The poem begins with “Some mistakes are known as betrayal, and you have transgressed and betrayed”.

“You traitor, you betrayed the most precious trust, you exposed your games and nature,” he added in the piece. The royal then continues to accuse his wife of lying, suggesting the claim was backed by evidence. “You no longer have a place within me, go to who has kept you occupied”, he wrote, ending with “I do not care whether you live or die”.

While the subject behind the poem was not disclosed by al-Maktoum, the tone suggests it was addressed to a woman who had betrayed him.

Rumours of Haya’s escape were first aired by website Emirates Leaks on June 23, which alleged that she fled with the help of a German diplomat. German authorities have not confirmed any of the claims.

Princess Haya bint Al Hussein, 45, is the daughter of Jordan’s late king and the sister of current King Abdullah. She married into the Al Maktoum dynasty in 2004.

Sheikh Mohammed is the ruler of Dubai and prime minister of the UAE, as well as being among the world’s wealthiest individuals.The rumours raise “serious questions” about what may have caused her to flee, adding it indicates her life was in danger.
