There is a “crescendo of concern” from psychological experts that a vulnerable man was convicted of murder on the basis of a false confession, the court of appeal heard on Wednesday.

Oliver Campbell was convicted of murdering east London shopkeeper Baldev Hoondle 33 years ago after telling police he had shot him. But Campbell, 53, suffered profound brain injuries as a baby, leaving him with significantly impaired cognitive ability.
