Declared interests
MPs must register financial interests within 28 days. This is the register’s own text, republished verbatim from the official Register of Members’ Financial Interests. Registering an interest is a requirement met, not a finding against anyone.
Donations and other support (including loans) for activities as an MP
- Unison - £2,000.00 (registered 5 January 2026)

Voting record
In the 418 recorded divisions where Keir Mather and at least one other Labour member were recorded voting, Keir Mather voted the same way as most voting Labour members 418 times (100.0%).
This compares Keir Mather with other members of their own party who were recorded voting in the same division. It is not a measure of loyalty to a whip: Civometry holds no whipping records, so it cannot say which votes were whipped, and voting differently from party colleagues is not described here as a rebellion. Members not recorded in a division are excluded from the comparison rather than counted, because an absence from a division list is not a vote and does not mean the member was absent from the House.
Donations reported to the Electoral Commission
The register holds no donations reported against this name. Donations are matched on the regulated entity name exactly as the Electoral Commission publishes it; a member who reports under a different form of their name will not match here, and no similar name is substituted.

These are the running costs of an MP’s office and staff, claimed within IPSA’s rules and paid by IPSA; they are not the member’s salary and not personal income. A claim is a claim, not a finding. Staffing costs are published by IPSA in aggregate categories, not per employee.
