Question to the Home Office:

To ask the Secretary of State for the Home Department, how many investigations into deprivation of citizenship are currently being undertaken by her Department.

We do not comment on referrals or ongoing investigations but do publish information in respect of cases where a deprivation order has been served.

Figures for conducive deprivation orders, which are made under Section 40(2) of the 1981 British Nationality Act, have been published as part of the transparency report on disruptive and investigatory powers. Three reports have been published to date in 2015, 2017 and 2018:

Section 40(3) of the 1981 British Nationality Act, allows for deprivation of citizenship where fraud, false representation or concealment of material facts have been used to obtain British citizenship. Since February 2020 these figures have been published via the Transparency report on asylum data, which can be found using the links below:
