Citizenship

My Lords, I invite the noble Lord, Lord West, to return to the disqualification which visits a person who has served a sentence of imprisonment. In reply to my noble friend Lord Hylton, the Minister referred to imprisonment or the commission of a serious offence. Which yardstick is to be relevant? The Statement refers only to the fact of a prison sentence. Does that mean that a person sentenced even to a few days of imprisonment would fall foul of this provision? If so, in my respectful submission, that would be unjust and unreasonable, and would fail the sublimely reasonable test of WS Gilbert of making the punishment fit the crime.
