Imagine you are a whistleblower and want to leak data to the public. UK Libel and defamation law doesn&#x27;t apply to things MPs say in the House, and MPs can much easier get press attention than some random blogger. Hence it makes sense to work with a sympatheic MP to get the information into the public sphere.<p>In this sense, the MP is acting more like a journalist with a source. The source should be protected.
