asked Her Majesty's Government:

On how many occasions Ministers or government departments, on receiving a draft decision notice from the Office of the Information Commissioner on a complaint under the Freedom of Information Act 2000, have asked to make representations on points of substance; in how many of those cases the Information Commissioner agreed to make alterations to the decision notice; and whether they have plans to review the process so as to ensure that in future complainants are made aware of draft decisions and of any alterations made at the behest of Ministers or departments.[HL6631]

This information is not collected centrally. The Information Commissioner is responsible for the content of his decision notices.
