House of Commons copyright and YouTube

Apparently, the speaker of the House holds copyright on CPAC coverage of the House of Commons.

So when somebody uses that footage to create a parody (i.e. political commentary), the House can ask for it to be taken down as an infringement of copyright.

According to The Tea Makers, this has happened recently.

Surely it shouldn't be possible in any democracy for the government to suppress political speech ?
