By Rohith Nair Aug 5 (Reuters) - FIFA apologised to its members for mistakes made over its abandoned proposal to sell commercial rights to the World Cup as the body's leadership reaffirmed its support for President Gianni Infantino after a crisis meeting in Morocco on Wednesday. The proposal to sell a 20% stake in a new commercial rights entity to private investors in a deal that would have raised about $4.2 billion provoked a fierce backlash and was withdrawn last Friday.
