UK must curb disinformation in political ads

Internal threats to electoral integrity

Electoral integrity in the UK faces threats from within. Political parties run campaigns that spread inaccurate information. Commercial ads follow strict rules to ensure accuracy. Political advertising remains in a grey area. This lack of oversight is critical. Elections are decided by tiny margins.

Close margins amplify the risk

May local election data shows the stakes. In 41.4% of English constituencies, victory came with less than 5% difference. Nine results were decided by a single vote. The Brexit referendum ended 51.9% leave versus 48.1% remain. That is a mere 3.8% margin. Misleading messages can easily flip such close outcomes.

External interference and internal disinformation

MI5 chief Ken McCallum warned against exaggerating Russian interference. Andy Burnham’s comments highlighted the issue. Yet an equally serious threat comes from inside. Political parties and their campaigns spread disinformation. Factual claims in election ads remain unregulated. This contrasts sharply with commercial advertising standards.

Legislative opportunity

The 2020 House of Lords committee recommended regulating factual claims in election ads. The current Representation of the People Bill offers a unique chance to act. An amendment covering this area was backed by 37 MPs in the Commons. Collaboration with Lords members is being finalized to advance the proposal.

Accountability and AI assessment

Burnham signed our voluntary code for honest election advertising in 2024. This code forms part of the proposed amendments. We must address foreign interference, but we cannot ignore disinformation from our own parties. MI5 confirmed Russia tried to interfere in the Brexit vote. If Russian efforts changed the voting intentions of just 2% of citizens, the leave majority would have eroded. Those voting remain would have won. We recommend MI5 use the latest AI technologies to assess the impact. This step is essential for introducing a new referendum.
