But not even a “lazy” Freedom of Information request could reveal the correspondence between Department and the NI deputy First Minister.. From the BBC report

Under the Freedom of Information Act the BBC requested correspondence between Mr McGuinness and the Department of Culture but the request was denied on the grounds that the disclosure could have a detrimental impact on the process of finalising the report.
