A person is disqualified for membership of the House of Commons if, on the day on which he is nominated as a candidate, he has not attained the age of 18.

Subject to an order made by the House of Commons under section 6(2) of the House of Commons Disqualification Act 1975 (c. 24) as applied by subsection (3), if a person disqualified by subsection (1) for membership of that House is elected as a member of that House his election is void.

Sections 6(2) to (4) and 7 of that Act apply in the case of a person disqualified by subsection (1) as they apply in the case of a person disqualified by that Act, and references in those sections to a person disqualified by that Act must be construed as including references to a person disqualified by subsection (1).
