Number 10 were at loggerheads with the new justice secretary last night over protecting the identity of suspected sex offenders.
Robert Buckland, QC, claimed people arrested on suspicion of rape should remain anonymous until charged - if they have reputations to protect.

Earlier this year Cliff Richard launched a campaign to ban the naming of sexual crime suspects unless they are charged
