Question for the public body
What explains the gap between the recorded signing and publication dates?
Documents and records to verify
Check both dates against BASE and the signed contract. Ask when the record was submitted and whether it was corrected.
This observation does not establish favouritism, illegality or loss. Verify the documents and seek the public body’s explanation before publishing.
Supplier totals use published shares; where unavailable, equal allocation is an estimate.
