Temporary exclusion orders have been used several times since they were introduced in 2015.
The last publication of the Annual Transparency Report on Disruptive and Investigative Powers published in February 2017 confirmed that the power had not been used as at the date of that publication.
The next Annual Transparency Report, due for publication in Spring 2018, will confirm how many times the power has been used during 2017.
The Counter-Terrorism and Security Act 2015 requires a permit to return to be issued to facilitate the return of a UK national who is subject to a temporary exclusion order, if the subject applies for one, or if they are being deported to the UK. Permits to return have been issued on several occasions.
