The trial of a person sent for trial—
shall not begin until the prescribed minimum period has expired except with his consent and the consent of the prosecutor;and
shall not begin later than the expiry of the prescribed maximum period unless a judge of the Crown Court otherwise orders.
For the purposes of this section the prescribed minimum and maximum periods shall begin with the date when the defendant is sent for trial and the trial shall be taken to begin when the defendant is arraigned.
