All of Europe is leftist in that regard. There is no free speech in Europe and even the "extreme right" parties in France, Italy, Germany or Romania, for example, are just called extremist because anyone can throw words at anything, not because they are (note: LePen the father was an extremist, the daughter is not).
OSA is a product of the last Tory government who, I can promise you, were not at all "leftists".
