Question to the Home Office:

To ask the Secretary of State for the Home Department, which websites detainees in each immigration detention centre are blocked from accessing.

The details of individual blocked websites are not held centrally and could
only be obtained by examination of information held at each immigration removal
centre (IRC) at disproportionate cost.

Internet access is not standardised across all IRCs although a review of access
is being undertaken to address this.

Suppliers operating IRCs on behalf of the Home Office use specialised software
which screens out prohibited categories of sites or sites whose addresses
contain prohibited key words rather than blocking individual website addresses.
Prohibited categories are based on safety and security concerns, for example
potential terrorist or pornographic sites.
