First Minister Swinney has denied allegations that SNP parliamentary resources were used for campaigning purposes. In response to fresh claims, Swinney stated that Parliament stamps were not used for campaign activities. The first minister emphasized that the SNP is committed to following all rules and regulations regarding the use of parliamentary resources.

The SNP is currently under investigation by Holyrood authorities for potential misuse of MSPs' expenses in funding campaigning for the general election. An anonymous complaint was sent to the Scottish parliament's presiding officer, Alison Johnstone, alleging that stamps paid for on expenses were given to Westminster election candidates for posting leaflets to voters.
