The parents of Madeleine McCann are taking part in an ITV documentary to mark the first anniversary of their daughter's disappearance.
Cameras have been following Kate and Gerry McCann since January for the programme, which will feature extended contributions from the couple.
The one-hour ITV1 special follows Madeleine's parents as they launch a campaign to introduce a US-style Amber Alert system in Europe when a child goes missing.
The couple have already been filmed at their home in Rothley, Leicestershire, and travelling to Washington in the US to pursue their campaign. Cameras will also be with the pair when they intend to highlight the issue in Brussels.
The alert system would see law enforcement agencies empowered to commandeer airtime on TV and radio when a child goes missing.
ITV said the McCanns hope a European-wide scheme would help other families in similar circumstances.
In the documentary, the McCanns also talk about Madeleine, the night the four-year-old went missing, becoming "Arguido" suspects in Portugal and the decision to return to Britain.
A statement from the broadcaster said: "ITV has commissioned Mentorn Media to make a documentary marking the first anniversary of Madeleine McCann's disappearance and focusing on the campaign to prevent others going through a similar ordeal."
It said no payment has been made to Madeleine's parents for making the programme and the broadcaster will instead donate £10,000 to the Find Madeleine Fund.
Madeleine went missing from her family's holiday apartment at the Ocean Club, in Praia da Luz, Portugal, on May 3.
