Question to the Ministry of Defence:

To ask His Majesty's Government whether they will review the provisions of the Foreign Enlistment Act 1870 to provide exemptions and protection from prosecution for British citizens who have served in the armed forces of Ukraine.

Foreign, Commonwealth and Development Office travel advice to Ukraine states: 'If you travel to Ukraine to fight, or to assist others engaged in the war, your activities may amount to offences under UK legislation. You could be prosecuted on your return to the UK'.

The Crown Prosecution Service, which acts independently of police and Government, will consider any information that is referred by the police and any decision to prosecute will be considered on a case-by-case basis and in accordance with the Code for Crown Prosecutors.
