Many situations that put people at risk of statelessness were resolved after 30 April 2003, when the Nationality, Immigration and Asylum Act of 2002 came into force. As a result of this act, the United Kingdom gave most people with residual British nationality but no other citizenship the right to register as full British citizens. However, there are still some people who have not been able or willing to register as citizens. Following the publication of a joint UNHCR-Asylum Aid report in 2011, the UK adopted a statelessness determination procedure in 2013.
