A former Bishop of Rochester, Dr Michael Nazir-Ali is calling for a burka ban in places like Parliament and Whitehall.Dr Nazir-Ali, who led the diocese of Rochester for 15 years, said the ban should be introduced for ‘national security’ reasons.It comes after former Foreign Secretary Boris Johnson said women who wear face-covering veils looked like "bank robbers" and "letter boxes".We were joined by Gillingham Imam Safeer Khan to talk a bit more about the issue.
