The Home Office received the official request from detectives today as funding for Operation Grange begins to run out.
More than £11million has far been spent on trying to find Madeleine who went missing in Portugal on May 3, 2007.
It is hoped the extra funding, which will see investigations continue until March 2020, will bring new hope in finding Madeleine.
What are the thoughts on this request for more funding? Heartbreaking though it must be for her family, is it time to stop?
I've got another 'keen'... Ouch!
