Question: What is the nickname of the current president of Rebels MC?

Related documents: [0]  [DOC] Alessio Emmanuel "Alex" Vella (born 1954), or The Maltese Falcon, is a Maltese businessman, former boxer, stand over man and National President of the Rebels Motorcycle Club in Australia. Despite having lived in Australia since the 1960s, he is not a citizen of the country. This caused visa problems when he tried to return to Australia after having gone to Japan with his son Adam (also a boxer) for a boxing match in 2007. The New South Wales Police Force tried to bar Vella from re-entering Australia then, but he was eventually allowed to return. In 2014 Vella visited Malta, and his residency visa was cancelled by the Minister for Immigration and Border Protection. Vella tried to appeal in the High Court in October 2015, but was not permitted to. [END]

It was founded by Clint Jacks in Brisbane, Queensland in 1969 and was originally named the "Confederates". Their insignia is a Confederate flag with a cap-wearing skull and 1% patch in the centre. The Australian government and law enforcement consider the Rebels to be a criminal organisation but the club claims to be a group of motorcycle enthusiasts rather than gangsters. The National President is currently former Maltese boxer Alex Vella. [END]
