It is the first time the couple had returned to Portugal since 2007
The parents of missing girl Madeleine McCann have returned to Portugal together for the first time in more than two years.
Kate and Gerry McCann met lawyers in Lisbon but did not visit Praia da Luz, where Madeleine disappeared in 2007.
It is understood they held discussions with their legal team and a PR agency on ways to advance the search.
Mr McCann said private investigators were still looking at "hundreds of thousands" of pieces of information.
The one-day trip was the first time the McCanns, from Rothley, Leicestershire, had returned to Portugal as a couple since September 2007.
Mr McCann has visited Portugal on two other occasions in the past two years, most recently in April to advise private detectives filming a reconstruction.
Gerry McCann: "There is no evidence that Madelaine is dead"
The couple are taking legal action against one-time investigating officer Goncalo Amaral, after winning a gagging order against the publication of his book, which claimed Madeleine was dead.
The Truth Of The Lie had hampered the search and added to Kate and Gerry McCann's distress, a judge said earlier this month.
Any potential compensation - which advisers have said could be more than £1m - would be ploughed back into the search for Madeleine.
At a news conference, Mr McCann said there was no evidence his daughter, who was four when she went missing, was dead.
Mrs McCann said: "Our main worry, obviously, was people believing that Madeleine was dead.
"If people believe that she is not alive, then people will stop looking for her."
She added she had gained a new hope for her daughter following the discovery of Jaycee Dugard, who was found in California last month, 18 years after being kidnapped.
