My question is to the Minister for Immigration and Citizenship. I remind the minister that the government granted a visa to hate-preacher Taji Mustafa to speak at the Hizb ut-Tahrir conference yesterday, despite the coalition requesting on numerous occasions, and again last week, that he not do so. I also remind the minister that he ruled out revoking the visa yesterday. Will the minister explain why the government allows preachers of hate into our country?
