The UK's independent child abuse inquiry says it is going to run 12 different investigations.
The Anglican and Catholic churches and "certain people of public prominence associated with Westminster" will be investigated by the independent abuse inquiry, it has been announced.
Justice Lowell Goddard, who is leading the investigation, also said councils in Lambeth, Nottinghamshire and Rochdale will be examined.
Inquiry subjects
She set out 12 different areas which will come under scrutiny.
Justice Goddard said: "The investigation will focus on high-profile allegations of child sexual abuse involving current or former members of parliament, senior civil servants, government advisers and members of intelligence and security agencies.
"It will consider allegations of cover up and conspiracy and review the adequacy of law enforcement responses to these allegations."
It will also focus on abuse in the Roman Catholic and Anglican churches, she said.
The inquiry was established last year after claims of a high-level cover up of abuse and has been hit by delays after two of the previous chairwomen resigned.
It will be the largest ever public inquiry in Britain and is expected to take up to five years and cost tens of millions of pounds.
