What Parliament records
This category records certain family members engaged in lobbying on behalf of someone else, where Parliament's rules require the MP to register the connection.
How the 2025/26 figure works
We show any category 10 records newly appearing in complete register comparisons during this financial year. These entries have no common financial value or travel duration to rank.
This category has no comparable value-based top ten. See this year’s category →
What the figure leaves out
The entry describes a family connection, not a payment to the MP, and registration alone does not imply improper conduct.
Only records available in complete compared register editions are included. Registration does not imply wrongdoing.
