Imagine you are a whistleblower and want to leak data to the public. UK Libel and defamation law doesn'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. In this sense, the MP is acting more like a journalist with a source. The source should be protected.
