Cotswolds - The siblings will compete in the London 2012 Olympic Ass of the Year race over seven furlongs it was announced today.
The new event in the Olympic Schedule has been described as made in heaven for the bruvvers after both showed some amazing grip during bumpy career rides.
Cameron Major famously defended notorious Tory Party perjurers Jonathan Aitken and Geoffrey Archer and is one of the UK's top pro criminal barristers with some astonishing form.
His younger brother Dave is a dab hand at trail riding - or hacking as it is known - as witnessed by this week's stories of him sitting astride the Met's retired glossy chestnut mare Raisa during her two year stay at nearby Chateau Brooks Home Farm.
Commenting on the week's headlines a Pratts Bottom Donkey Sanctuary stable hand told QM-NewsCorpse he'd been impressed by Alex Cameron's riding skills despite being a bit frightened of him at their first meeting.
"It was a very blustery day," Rory McPiggot commented, "and Alex Cameron's wild windswept silver tresses made him look a dead ringer for that Serbian warlord, whatssisname...Slobbo Milosevic.
"Fortunately a hard hat soon changed that spooky appearance to the kindly Sanctuary supporter we all know him to be."
The donkey retirement home has apparently been grooming a pair of its top asses to be ready in time for the Olympics debut at Greenwich Park in August this year.
It is hoped other famous siblings from foreign competitor nations will also join the event which is being sponsored by Shergar Holdings plc.
Lester Piggot is 104.
