The doctor treating 'Robert' says that over 50 days of memory loss is extremely rare and throughout his whole career he's never met someone with no memory at all.

The medical team have taken the man to the town centre of Peterborough where he was found and also to Wisbech, an area with several Eastern European communities, as he has a slight accent.
But doctors say that even if he's identified, the process to bring back his memory will be just beginning.
