A major appeal is to be made on Greek television by both South Yorkshire police and the family of Ben Needham to try and find Ben who vanished as a toddler on the holiday island of Kos almost 24 years ago.
The detective leading the new - year long inquiry - into his disappearance will be alongside Ben's mother Kerry, grandmother Christine and sister Leighanna in Athens on Friday night to make the appeal.
Also travelling to Greece to appear on the programme will be Calendar's producer Mark Witty who has made a film which will be shown to millions on Friday.
South Yorkshire Police will make their first ever television appeal in Greece on Friday for information about the disappearance of Ben Needham
Two officers, including Detective Superintendent Matt Fenwick who is in charge of the case in the UK, will appear alongside Ben's mother Kerry, Ben's grandmother Christine and sister Leighanna.
The programme, called "Light at the End of the Tunnel" features cases of missing people and reaches millions of viewers in Greece. The show will give information about "Operation Ben" which was launched after a recent Home Office grant of £700,000 .
Calendar producer Mark Witty has also been invited onto the show by producers - the programme will feature two films made by Calendar as part of the appeal. ITV Yorkshire and "Light at the end of the Tunnel" have co-operated considerably since the 20th anniversary of Ben's disappearance in 2011.
Appeals made by the show, with Calendar's help, have brought forward a number of people with information. Some of the people who contacted the programme are being contacted by South Yorkshire Police as part of Operation Ben.
Ben disappeared from the Greek island of Kos in July 1991. Since then there have been hundreds of sightings but no trace of the toddler, who was 21 months old at the time.

Three generations of Ben Needham's family have travelled to Greece to follow up one of the strongest leads they've ever had since the toddler's disappearance.
Ben vanished from the holiday island of Kos in 1991 - but over the last few months his mother Kerry was contacted by someone who thinks he's Ben.
Kerry, his grandmother Christine and sister Leighanna went to meet him on mainland Greece.
The mother of Ben Needham, who went missing from Kos 24 years ago this July , hopes an open letter to her son will prompt more people to come forward with information.
Kerry Needham posted the message on her website asking for anyone who believes they might be Ben to get in touch, and telling her son that she loves him.
The message has also been translated into Greek, to target certain Facebook communities in the country.
The mother of missing toddler Ben Needham has issued a direct appeal to her son who went missing in Greece more than 20 years ago.
Kerry Needham has written a message on her website asking for anyone who believes they might be Ben to get in touch, and telling her son that she loves him.
Ben, from Sheffield, vanished on July 24 1991 after travelling to the Greek island of Kos with Mrs Needham and his grandparents.
Over the years there have been a number of possible sightings and a range of theories about what happened to the youngster, who would now be 25.
The message, which is also translated into Greek on the Help Find Ben Needham website, reads: "This is a direct appeal to anyone who is around 25 years old and possibly living with a family who you look nothing like, I beg you to get in contact with me.
"I promise to cause no problems for your family who you live with, I just want you to know the truth about what happened to you and to know you are healthy and happy.
"A simple DNA sample can be taken from you without causing any distress to anyone. So if you think you were born in 1989 and you have blue/grey eyes and a possible birthmark on your leg, YOU could be Ben!!!<
"Twenty-three years have gone by Ben and I love you just as much today as I did the day you were born, please anyone get in touch and end all this pain your family feel living without you."
Last month, the Home Office agreed to fund a team of British detectives to help search for the youngster after Ben's family engaged human rights barrister Ian Brownhill to help them.
South Yorkshire Police asked for the financial help to follow up information the family believe has never been properly investigated.
The funding is for the financial year from April 2015 and is for up to £700,000.
Ben's family have said they want South Yorkshire Police to investigate leads, including a file they have handed in that lists eight separate sightings from unconnected people of a boy who could potentially be Ben with the same Greek family.
The Home Office backed a South Yorkshire Police operation in 2012 when land was excavated on Kos, near the farmhouse from where Ben went missing. No trace of the boy was found.
Last year, a DNA test on a young man featured in video footage shot in Cyprus proved negative.
