It is more than 13 years since three-year-old Madeleine McCann vanished from the Portuguese coastal village of Praia da Luz while on holiday with her parents, Kate and Gerry, and siblings.

As the Metropolitan Police have identified a suspect, here is a timeline of events surrounding her disappearance and some of the developments over the following years.

2007

– May 3: Kate and Gerry McCann, from Rothley, Leicestershire, leave their three children asleep in their holiday apartment in Praia da Luz in southern Portugal while they dine with friends at a nearby tapas restaurant.

Nothing is amiss when Mr McCann checks on the youngsters just after 9pm, but when his wife goes back at about 10pm she finds three-year-old Madeleine missing.

Jane Tanner, one of the friends dining with the McCanns, reports seeing a man carrying a child earlier that night.

Officers also search the home he shares with his mother in Praia da Luz, just 100 yards from where the youngster vanished.
