Ahead of the Senedd election, around 1,300 people in Cardiff do not receive postal ballot papers due to an error involving supplementary voting packs, according to multiple reports. BBC News and The Independent say the issue is linked to printing rather than delivery. Initially, Cardiff council attributes the problem to Royal Mail in response to complaints about missing ballot materials. The council later revises its explanation, stating that some ballot packs have not been printed in full. The Independent reports that the council says the scheduled print run for supplementary voting packs did not fully take place last week. As a result, some eligible voters expected to receive ballot papers by post are left without them in time for the election process. The reports describe the situation as a postal voting administration failure affecting a limited number of voters, with the authority working to address the missing packs. Both outlets present the same core facts: the scale of the impact is about 1,300 voters, and Cardiff council’s revised account points to incomplete printing of supplementary voting packs.
