What would be the difference between a solicitor and barrister in the CPSWatch this thread
Solicitors- write indictments, decide charges, gather evidence
Barristers- Represent and build a case?

Barristers represent; solicitors advise on the law and in this case ultimately make charging and proceeding decisions in line with the law.
The CPS does have "in-house" Barristers who present cases in the Crown Court on behalf of the Crown. These cases are generally the more serious cases. The majority of cases in the Crown Court however are presented by your classic Barrister who is a member of a chambers, authorised by the CPS to present cases on behalf of the crown.
Solicitors will indeed draft indictments and decide charges. They play absolutely no role in the gathering of evidence.
Barristers will present a case to the court. In terms of "building" a case, they will merely use the evidence provided to them by Police to present an effective case.
