Question to the Home Office:

To ask Her Majesty's Government, for each of the last five years including this year to date, how many Commonwealth citizens have been detained following residence in the UK for over (1) 30, (2) 40, and (3) 50, years, (a) following a criminal conviction, (b) after a failure to provide sufficient evidence showing proof of residence, and (c) for other reasons; and in each case how many were subsequently deported.

Providing the information requested would require a manual check of individual records which could only be done at disproportionate cost.
