Madeleine McCann’s parents have lost a THIRD appeal to silence a cop who wrote book about them and the hunt for their missing daughter.

Goncalo Amaral claimed in The Truth Of The Lie that Maddie died in her holiday apartment and that Kate and Gerry McCann covered up her death.

Now judges have dismissed the McCann's bid to overturn a decision to uphold the detective's right to publish a tell-all book about them.

Earlier this week the 'Official Find Madeleine Campaign' Facebook page reopened after it was forced to close because of internet trolls.

Glasgow Times:

The page's webmaster wrote: "I have turned the page back on for now, but will continue to turn the page off if we receive hateful posts."

Madeleine disappeared in Praia da Luz in Portugal in May 2007 aged three.

Her parents, Kate and Gerry McCann, have vowed to "never give up" hope of finding their daughter.

Since 2011, the Metropolitan Police have been assisting with the search for clues about what happened to the youngster, with officers visiting the holiday resort in 2014.
