The Freedom of Information Act
The FOI gives you the right to ask any public body for all the information they have on any subject you choose. Also, unless there's a good reason, Public authorities must comply with your request promptly, and should provide the information to you within 20 working days (around a month). If they need more time, they must write and tell you when they will answer, and why they need more time. Knowsley Council, being a public authority, are covered by this act; here's what they say on their website:
"The public has a general right of access to all types of recorded information held by public authorities, including the council. Freedom of Information is part of a wider group of national policies which have the aim of modernising government and showing people how it is working on their behalf.
"When a person requests a piece of information, the council has a duty to disclose that information, if it holds it, and it is not subject to any legally defined exemptions.Knowsley Council has published a publication scheme which shows what information can already be accessed. Any information which is not part of the Publication Scheme can be requested under the Freedom of Information Act 2000."
