Former Director of Public Prosecutions, Lord Macdonald QC, has criticised the police after they said their "Plebgate" inquiry will "take as long as it takes".
Police are investigating claims that former Conservative cabinet minister Andrew Mitchell called police officers "plebs" in September 2012, something he has always denied.
Speaking on the BBC News Channel, Lord Macdonald QC, said that a year after an incident, which had lasted around 45 seconds, Mr Mitchell had been left "kicking his heels".
He said the delays in resolving the case were unacceptable.
