Wales approved a new law that seeks to prevent politicians from making or publishing false or misleading statements about facts with the intention of influencing the outcome of an election.
The measure was approved by the Welsh Parliament in March 2026 and requires the Government to subsequently establish the rules that will determine how this prohibition will be applied. It is not simply about banning any opinion or mistaken assertion: the legislation targets statements presented as facts and deliberately made to influence voters.
The initiative has sparked intense debate because it involves directly intervening in what candidates can say during an election campaign. Its supporters argue that new technologies, artificial intelligence and disinformation make it necessary to protect voters from deliberately false claims.
But its critics warn of the enormous challenge of determining what is a lie, what is an opinion, and who should decide, especially when a political statement may be debatable or interpreted in different ways.
In fact, Parliament itself acknowledged that the measure must have clear limits and be proportionate so as not to unjustifiably affect freedom of expression.
The proposal has been presented as a pioneering measure, but it has also prompted an uncomfortable question: how far can a government go in preventing politicians from lying without ending up controlling what they can say during a campaign?
