Should your government be able to take away your citizenship?

In the United Kingdom, the government has had the legal authority to revoke naturalized Britons' citizenship since 1918. But until the terrorist bombings on the London transport system in 2005, this power was rarely exercised. Since then, the British government has revoked the citizenship of 42 people, including 20 cases in 2013. British Home Secretary Theresa May has said that citizenship is "a privilege, not a right."

Most of the 42 held dual nationality. Mohamed Sakr, however, did not. His parents came to Britain from Egypt, but he was not an Egyptian citizen. Therefore, by stripping him of citizenship, the U.K. government made him stateless.
