SYDNEY - The Catholic Archbishop of Adelaide was Tuesday charged with concealing child sex abuse and has taken leave from his high-level Australian position to fight the allegation. Philip Wilson was charged by New South Wales police in relation to an offence allegedly committed during the 1970s by known-paedophile priest Jim Fletcher, now dead, when both men worked at a diocese near Newcastle, north of Sydney. Local media said the 64-year-old is thought to be the most senior Catholic official in the world to face charges of this nature, and if sentenced could face up to two years behind bars.
