This petition was rejected

The Government e-Petitions Team gave the following reason:

Petitions need to call on the Government or Parliament to take a specific action. We're not sure if you want the Government to publish data relating to arrests or relating to convictions ('people committing offences'/'criminals'). You could start a new petition explaining clearly what you would like the Government or Parliament to do.

In respect of nationality data, the Ministry of Justice already includes data on the nationality of persons within the prison system in its quarterly offender management statistics, here: www.gov.uk/government/collections/offender-management-statistics-quarterly

In addition, the Home Office has committed to review the data that it collects and publishes regarding the nationalities and offences committed by foreign national offenders who are subject to deportation proceedings. Further details of that review process can be found here:
