Outgoing Fifa president Sepp Blatter has vowed to "fight" after being hit with an eight-year ban from football.
"Suspended for eight years - suspended for what?" he demanded, speaking at a press conference in Zurich following the decision of the Independent Ethics Committee.
He confirmed he plans to take his objections to Fifa's appeals body, go before the Lausanne-based sports arbitration panel, or take legal action under Swiss law if needed.
He said he had served with "heart and conscience" for more than 40 years, and criticised the committee for its handling of the investigation, saying he felt he had been "betrayed".
"I am a man of principles, and these principles are: Never take money you have not earned; secondly, pay your debts - but now they are telling me that I tried to buy votes through Michel Platini votes for the 2011 elections," he added.
Michel Platini will be able to attend Euro 2016 matches in France next summer despite his Fifa ban - but only if he buys a ticket as a fan.
