I was surprised to read that some Muslim majority countries ban them, but good old Wikipedia said this:
There are currently 24 states that have banned the burqa and niqab, both Muslim-majority countries and non-Muslim countries, including:
Africa: Cameroon, Chad, the Republic of the Congo, Gabon, Senegal, Tunisia, Zambia
Asia: China, Kazakhstan, Kyrgyzstan, Sri Lanka, Tajikistan, Turkmenistan, Uzbekistan
Europe: Austria, Belgium, Bulgaria, Denmark, France, Italy, Luxembourg, the Netherlands, Switzerland, Portugal
Interestingly, there was also a reference to Muhammad Sayyid Tantawi, an Egyptian Islamic scholar who served as the grand mufti of Egypt and then as grand imam of al-Azhar who issued a fatwa in October 2009 arguing that veiling of the face is not required under Islam and that the niqab is a cultural tradition without Islamic importance. Other posters said the same.
However, I cannot see a ban ever being enacted here. A combination of strong Muslim support including from within political parties and well intentioned liberal progressives would never allow a ban to occur. Maybe 20 years ago as some countries did, but not now. And likely, even 10 years ago, I’d also have argued that a ban was unfair based on a belief in religious freedom. Now, the rapid increase in women wearing the burka and niqab is concerning.
