Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many recipients are there of a.) housing benefit b.) pension credit c.) any other benefit support in i.) polygamous married ii.) aunt-nephew or uncle-niece married households.

Based off the most recent published data (March 2026) from the Housing Benefit Single Housing Extract (SHBE), there are fewer than ten households where the claimant is recorded as having more than one partner. This has been used as a proxy for polygamous marriage.

The other information requested is not held. I refer the hon. Member to the answer given on 1 June 2026 to Question UIN 2859.
