What grounds would amaral... A convicted perjurer and therefore liar........ Have to sue the UK press
Maybe you don't understand what libel is. The papers print something untrue and anyone can sue them, no matter how 'naughty' others think they have been.
'"The news published by the Daily Mail and other British newspapers about
an alleged lawsuit I would have brought against the McCann is completely false. I did not file any lawsuit or demand any compensation from the McCann", Gonçalo Amaral told us, today after questioned about a story published by that tabloid, saying that the McCann may have to pay him 750,000 pounds for compensation because of a complaint filed by him, wiping out the Fund for the search of Maddie.
"The case reported by the 'Daily Mail' concerns a complaint filled by the McCann themselves with the European Court of Human Rights in Strasbourg against the Portuguese State. If that court decides any compensation must be paid, it can only be the Portuguese State to pay them, McCann, for failures of the Portuguese Justice system. If they lose the case, they will never, under any circumstances, have to pay any compensation to anyone”, said the former investigator of Polícia Judiciária.''
