Given that he has been charged, he will now (if he has not already) appear in the Mags Court and then it will be sent straight to the Crown. At the MC, the court will order that anyone under 18 cannot be named by the press under the Children and Young Persons Act (I forget the year, think it is 1934). At the Crown Court the press may apply for that order to be lifted, but it is up to the Judge. If the def is convicted, the chances of his name being released is quite high.
If the press print the name while there is an order in force, they can be prosecuted for contempt.
I think it is fair he is not named unless and until conviction. It sometimes makes my blood boil though when women make false accusations of rape and their identity is forever protected whereas the poor defendant has his name splashed all over the papers. Sorry, off topic.
