Federal MP Richard Miller (MR) wants to ban the Islamic party, he told the Belga agency on Saturday.
His statement comes soon after the party published its manifesto. He confirmed he was worried the Islamic party would win a lot of seats at the next election. It has candidates in 28 Brussels and Walloon communes.
This week Redouane Ahrouch, one of the Islamic party's co-founders, said his party wanted to establish an Islamic state and introduce the Islamic charter in Belgium. Mr Miller said this was "unacceptable".
"This project is a threat to our freedom and the fundamental rights that are part of our Constitution", says Mr Miller.
