At around 8.30pm on May 3, 2007, Kate and Gerry McCann left their three sleeping children in their holiday apartment in the quiet Portuguese resort of Praia da Luz and headed out for dinner.

They thought that Madeleine, three, and 18 month old twins, Sean and Amelie would be safe just 83 metres from where they were dining at a tapas restaurant with the group of friends they were holidaying with.

Throughout the evening, the adults took it in turns to check on the kids.

At 10pm, it was Kate McCann’s turn.

When she arrived at apartment 5A, she knew immediately something was wrong.

Madeleine was gone.

What happened next is well documented. The story of the blonde toddler’s disappearance became a global news story.

Last year, a Netflix documentary, The Disappearance of Madeleine McCann, recounted the chain of events in detail, and offered several theories as to what may have happened to Madeleine, who would now be aged almost 17.

Kate and Gerry McCann refused to take part in the program, stating that it could impede the ongoing police investigation.

In a statement on their website, they said: “We did not see and still do not see how this programme will help the search for Madeleine and particularly given there is an active police investigation, could potentially hinder it.”

That said, they have never given up hope of finding their daughter and continue in their fight for information that might lead them to her.

Today, it has been 13 years since Madeleine went missing.

Writing on the Find Maddie and Facebook campaign websites, Kate and Gerry McCann said:

“It is now 13 years since we were last with Madeleine.

“Her 17th birthday is to follow in the next couple of weeks – the latter tangibly, painfully, bringing it home to us what we have missed and continue to miss as a family.

“It shows how easy it is to become complacent with our lives and circumstances, albeit a totally normal and understandable, human characteristic.”

Alongside a photo of Madeleine taken shortly before her disappearance, the couple added:

Who are Madeleine McCann’s parents? 

Kate McCann (neé Healey) was born in 1968 in Huyton, near Liverpool. She graduated in 1992 with a degree in medicine from the University of Dundee. Gerry McCann, born the same year as Kate, was also a medical scholar, in Glasgow. After working in obstetrics and gynaecology, Kate became a GP. Gerry worked in sports medicine before moving into cardiology.

The couple, described by friends as “inseparable,” met while working as junior doctors at the Western Infirmary in Glasgow.

They married in 1998 and had their first child, Madeleine, in 2003 after IVF treatment. Twins Sean and Amelie followed two years later. The family moved to Rothey in Leicestershire, when Gerry got a job as a consultant cardiologist at Glenfield Hospital in 2005.

Did the McCanns split up after Madeleine McCann went missing? 

While the McCann’s never actually split up, Kate has spoken about how close their relationship came to breaking point. In her book, Madeleine, Kate talks about how she withdrew into herself after Madeleine’s disappearance, ceasing to read, play music, or even have sex with husband Gerry.

She said that the fears a paedophile had taken Maddie very much played into that.

Kate wrote: “Tortured as I was by these images, it’s not surprising that even the thought of sex repulsed me.

“I worried about Gerry and me.

“I worried that if I didn’t get our sex life on track our whole relationship would break down.”

She also recalled how supportive Gerry was during the darkest days of their lives “He would put his arm round me, reassuring me and telling me that he loved me,” she wrote.

Where are the McCanns now?

Kate and Gerry McCann, both now 52, remain together and continue to fight for information about Madeleine’s disappearance.

They continue to make updates to their website where there is also a section asking for donations.

In 2014, Kate told the BBC that she has returned to Praia da Luz on several occasions.

“I do go back for personal reasons,” she said. “It’s obviously the last place we were with Madeleine and I still walk those streets and I guess try and look for answers. It helps me, most of the time.”

After Madeleine vanished, Kate quit her job as a GP to work for children’s charities. Gerry McCann is now a professor of cardiology and prides himself on having “established a national and growing international reputation as an expert in Cardiac MRI (magnetic reasoning imaging)” – or scanning, as reported by The Sun.
