Question to the Home Office:

To ask the Secretary of State for the Home Department, how many foreign nationals who have been convicted of a crime outside the UK and who currently live in the UK are being supervised by email by probation officers based in their native country.

The Home Office does not hold information on any overseas probation supervision occurring by email. Probation is a responsibility of the Ministry of Justice rather than the Home Office and it may be that they hold the information you have requested.
