The Green Party’s Sian Berry agrees to Reform Political Advertising’s campaign pledge for responsible election campaigning.

Reform Political Advertising are delighted that The Green Party are the first party to agree to their pledge as part of the campaigns running for the various elections on May 6th.

Sian Berry, Green candidate for Mayor of London stated: 

“”Lies have been peddled in election campaigns in this country for too long. Not only does this mean that liars win elections, but it also erodes the public’s trust in politics and politicians. Only by being honest with people will we win back trust. 

“Factual accuracy in political discourse is an essential part of a well-functioning democracy. We encourage all the other parties to sign up to this pledge, and ensure that all campaigning is transparent, fact based and honest”

Alex Tait, Co-Founder, Reform Political Advertising said: “we welcome the leadership being shown by Sian Berry and The Green Party in agreeing to our pledge for responsible election campaigning. 

Our Yougov research shows that 85% of UK voters think that ‘it should be a legal requirement that factual claims in political adverts must be accurate.’ In the absence of the political advertising content regulation that we are campaigning for the pledge is a way of showing to the UK public clear intent and commitment not to mislead them in a manner that was so prevalent in the 2019 general election”.

Phil Smith, Director General at the UK’s trade body for advertisers ISBA, stated: 

“Phil Smith, Director General at the UK’s trade body for advertisers ISBA, stated: 

“ISBA support Reform Political Advertising’s pledge and the wider campaign for content regulation for political advertising, placing it on the same footing as commercial advertising and holding it to the same standards.”

The pledge is simply:

We <name of party> will practise responsible election campaigning and pledge to:

1. make sure that when we make factual claims in our advertising they have been checked beforehand with authoritative and reliable sources.

2. source the evidence for our claim in the ad where feasible, or quickly make it available on request.

3. revise or withdraw any claims that an independent, nominated fact-checking service finds to be misleading.

Our nominated fact checking services are Full Fact, Channel 4 FactCheck and BBC Reality Check.

About Reform Political Advertising. 

Reform Political Advertising is a not for profit, politically neutral organisation campaigning for the modernisation of the rules for political advertising. A key aim for our campaign is the introduction of content regulation to prevent misleading claims. 

We believe that the open and honest debate of issues facing the UK is fundamental to the functioning of our democracy. However, our politics is suffering because of a refusal to reform political advertising.

Our review of 2019 General Election advertising highlighted some of the worst recent cases of misleading claims. Neither voters, opposing factions, the media, consumer groups, or legislators had any recourse whatsoever: there are no rules against false statements of fact in electoral advertising.

This is not an issue confined to lobby groups and political commentators: in 2019, we fielded research via YouGov that found that 85% of UK voters think that ‘it should be a legal requirement that factual claims in political adverts must be accurate.’ 

We are approaching all political parties campaigning for the local, Mayoral, Scottish and Welsh parliamentary elections on May 6th and asking them to agree to our election pledge.
