Missing Madelaine McCann's parents Kate and Gerry have made an impassioned plea to the Prime Minister to re-open the investigation into their daughter's disappearance.
Writing an open letter to David Cameron and describing him as a 'devoted father' and 'family man' the desperate couple begged the PM to conduct a review of all the information relating to Maddie's abduction.
This is what they wrote:
'Dear Prime Minister,
As a devoted father and family man, you know the importance of children. Our beloved eldest child, Madeleine, was abducted from Praia da Luz, Portugal, four years ago. Since then, we have devoted all our energies to ensuring her safe return.
Today we are asking you - and the British and Portuguese governments - to help find Madeleine and bring her back to her loving family.
We live in hope that Madeleine will be found alive and returned to us. One call might be all that is needed to lead to Madeleine and her abductor.
To this end, we are seeking a joint INDEPENDENT, TRANSPARENT and COMPREHENSIVE review of ALL information held in relation to Madeleine's disappearance. Thus far, there has been NO formal review of the material held by the police authorities - which is routine practice in most major unsolved crimes.
It is not right that a young vulnerable British citizen has essentially been given up on. This remains an unsolved case of a missing child. Children are our most precious gift.
Please don't give up on Madeleine.
Kate & Gerry McCann'
What do you think?
Should the British Government be investing time and money into finding Madeleine?
