(2-part post):
Stage 1: A hearing in a Magistrates Court,where it will recognised that the law requires the case to be transferred to the Crown Court.
Stage 2: A few weeks wait and then a committal hearing in the Magistrates Court.
Stage 3: Several weeks (or possibly months) before the first Crown Court hearing.
Stage 4 , etc: Yet more procedural delays before anything much actually happens. If you've indicated that you will be pleading guilty, any relevant reports can be completed during this time). The whole procedure wil take at least 6 months, and more likely around a year.
It should be noted that, at each stage above the court will have to decide whether to continue bail. You could theoretically be 'banged up', on remand, at any stage but, given that you've obviously been given bail initially, you'll probably continue to get it.
Stage 5: You'll be sentenced in accordance with the new sentencing guidelines which are about to be introduced. They'll probably be fairly similar to the current ones. See page 13 here:
