The timeline and accepted version of events surrounding Madeleine McCann's disappearance have "significantly changed", British police say.
The Metropolitan Police said a BBC Crimewatch appeal to be aired on Monday would feature "the most detailed reconstruction" of the case yet.
It will also feature e-fits of a number of men police want to find.
