David Beckham, JK Rowling Expected to Join 'Madeleine Day'

The parents of four-year-old Madeleine McCann, who was abducted in Portugal four weeks ago during holiday, have announced plans for a "Madeleine Day" to keep her disappearance in the public eye.

Gerry and Kate McCann are planning to feature world leaders, pop stars and well known athletes for the international day of events and appeals to find Madeleine.

Sir Elton John, David Beckham and former US president Bill Clinton are expected to join the appeal.
