The charges:
:: The first charge against Mrs Brooks details that, between July 6 and 19 last year, she conspired with her husband, Ms Carter, Mr Hanna, Mr Edwards, Mr Jorsling and "persons unknown" to conceal material from officers.
:: Mrs Brooks and Ms Carter are also said to have "conspired together permanently" between July 6 and 9 last year to remove seven boxes of material from the NI archive.
:: Mrs Brooks, Mr Brooks, Mr Hanna, Mr Edwards and Mr Jorsling are all named on the third indictment, accused of conspiring together between July 15 and 19 of the same year to "conceal documents, computers and other electronic equipment".
If guilty, the sentence:
The Crown prosecution Service (CPS) sentencing guidelines for perversion of justice recommends a minimum sentences of four months and maximum sentences of one to two years per incident. Specific perjury and witness intimidation statutes permit longer sentences and in theory the offence of perverting the course of justice can carry a penalty of life imprisonment. However there have not been any sentences above 10 years that have been passed in the last century for this offence.
