Fifa is set to appoint top human rights lawyer Luis Moreno Ocampo as the first head of the new ethics committee's investigation arm.. Ocampo, 66, has experience of leading war crimes investigations at the International Criminal Court. The Argentine is expected to be confirmed next month and will investigate allegations of corruption or ethics rules breaches. Fifa's single-chamber ethics committee failed to gather enough evidence to prosecute allegations of vote-rigging during the 2018 and 2022 World Cup bidding contests. A report by Fifa's anti-corruption adviser, Swiss professor Mark Pieth, called Fifa's past investigation of corruption allegations unsatisfactory with sanctions imposed both insufficient and clearly unconvincing.
