Kate and Gerry McCann are

launching their website in German this week in a bid to reach German tourists who were staying at the Ocean Club when Madeleine vanished.

Apart from British and Dutch holidaymakers, who've long been canvassed directly, there were also German tourists who may have left the resort without talking to police about potential evidence that's not been considered.

The McCanns have also given an interview to Bunte magazine in which they make new appeals for help in the search for their daughter who disappeared from the family's holiday apartment in May 2007.

The couple's lawyers are studying the recent 30-page judgement from Portugal in which former cop Goncalo Amaral won an appeal to republish his book the 'The Truth of the Lie' which the McCanns had managed to get banned.

They may appeal his appeal ahead of a full defamation claim they are still pursuing against Mr Amaral who claims that Madeleine died accidently in the apartment and her parents hid the "truth" by concocting an abduction theory.

A defamation trial in Lisbon is unlikely to be heard until next year.
