Mr Aronstam was among those paying their respects to Rashid this week. He wrote on his Facebook account: “Sheikh Rashid, I will miss you. You had faults but don’t we all.”
Another tribute was paid by the former Argentinian footballer Diego Maradona, who himself battled drug addiction. Mardona, who coached a Dubai football team in 2011, said: “He was a great horseman and a first-class athlete who impressed me a great deal.”
As a three-day period of official mourning ended in Dubai, officials have maintained a stony silence amid questions of whether the prince’s past could have contributed to his death. Instead, it is Sheikh Hamdan who has become the spokesman for his family’s grief – on Twitter.
