§ 36. Vera Baird
To ask the Solicitor-General what criteria apply in deciding whether to prosecute(a) serious fraud and (b) other criminal offences. 
§ The Solicitor-General
The Crown Prosecution Service (CPS) is the principal prosecuting authority in England and Wales, and as such it takes over and prosecutes the complete spectrum of criminal cases instituted by the police. This includes serious offences of fraud, although these cases can also be prosecuted by the Serious Fraud Office (SFO).
CPS decisions on whether or not to prosecute an offence, of any kind, are taken in accordance with the principles set out in the code for Crown Prosecutors, issued by the Director of Public Prosecution under section 10 of the Prosecution of Offences Act 1985.
The code acknowledges that each case is unique and must be considered on its own facts and merits. However, fairness and consistency in assessing these elements are promoted by applying a common framework of key principles, irrespective of the type of offence under consideration.
