A businessman is offering a £1m reward for information leading to the return of three-year-old Madeleine McCann.
Police are urging anyone with information to come forward
Stephen Winyard, who owns Stobo Castle in the Borders, told a newspaper he wanted to help her distraught parents.
Meanwhile, a prayer vigil will be held in Glasgow - where Madeleine's father Gerry comes from - eight days after she disappeared on holiday in Portugal.
Police said searches in and around the Praia da Luz resort were being scaled back as the results were "zero".
Mr Winyard, a 57-year-old father-of-three who lives in Monaco, said he was moved to offer the reward by photographs of Madeleine's distraught parents.
He told The Times: "When I saw their faces, I felt frustrated that no one else had yet come forward offering a substantial reward, and so felt compelled to do so myself."
The proposal has reportedly been passed on to the McCann family in Portugal, but it is currently unclear whether the country's laws will allow the offer to be formally put to the public. It is not the first reward to be offered in the case.
On Saturday a colleague of Madeleine's mother offered a £100,000 reward for help in finding the toddler.
The prayer service in Glasgow will appeal for the safe return of the child, who was abducted in the Algarve.

It has been organised by former medical colleagues of the girl's father, Gerry, who comes from the city.
St Andrew's Roman Catholic Cathedral will open its doors on Friday to host the service at 1900 BST.
Madeleine, from Rothley, Leicestershire, disappeared from her family's holiday apartment in Praia da Luz a week ago.
Celtic and Aberdeen players will also wear a yellow ribbon during Saturday's match at Celtic Park.
The clubs agreed to a request from Madeleine's aunt Phil McCann for the ribbons to be worn.
Celtic club captain Neil Lennon will also make an appeal for Madeleine's safe return to her family.
Celtic have requested police permission for fans to be allowed to hold up Madeleine's picture in the stands.
Monsignor Christopher McElroy, the cathedral administrator, said: "People of all faiths and none have watched with mounting anxiety as the search for Madeleine continues.
"The prayer service we are organising will help people to overcome that sense of helplessness which we all naturally experience.
"We will allow people the opportunity to reflect, to pray and to keep alive their hope that Madeleine can be found alive and well.
"The service is open to people of all faiths. Whether they want to come and simply sit quietly or light a candle, or join in the prayers and hymns they will be very welcome."
Archbishop Mario Conti of Glasgow, said: "Although I won't be able to be present at the vigil in person, due to prior engagements, I will be very much united with all who gather in prayer for Madeleine and her parents.
"My own prayers and those of countless others continue for the safe return of the little girl and an end to this horrific ordeal for the family."
Villagers in Rothley held a silent vigil for the family on Tuesday.
Phil McCann said she was in regular contact with Madeleine's parents in Portugal.
She said they were "overwhelmed" by the reaction in Scotland to their daughter's disappearance.
