“If an offender is convicted of a lesser or different offence from that originally charged, and has earlier made an unequivocal indication of a guilty plea to this lesser or different offence to the prosecution and the court, the court should give the level of reduction that is appropriate to the stage in the proceedings at which this indication of plea (to the lesser or different offence) was made taking into account any other of these exceptions that apply. In the Crown Court where the offered plea is a permissible alternative on the indictment as charged, the offender will not be treated as having made an unequivocal indication unless the offender has entered that plea.”
