Madeleine McCann, as you all must be aware by now, was abducted from Praia Da Luz in Portugal some 10 days ago. She will be 4 years old today.
One avenue that the authorities are investigating is that Maddie may have been taken across the Portuguese border into Spain. There has already been a widespread awareness campaign by groups of expats in various areas of Spain and Gibraltar.
You can help by posting a picture of Maddie in your local shops, bars, restaurants, wherever.
