This is a question I was asked when testifying before another committee and answered in my second language, which probably led to a misunderstanding.
The government doesn't muzzle me, obviously. I was referring to data that had been provided to my office and that the government, in this case the Department of the Environment and Climate Change, had explicitly forbidden me to disclose. That said, the government has not muzzled me with regard to the publication of a report or the content of any of the reports I have published.
