Goldman Sachs is conducting an internal investigation after one of its computers was used to try and rig a public vote on the ‘Robin Hood’ tax.

A group of not-for-profit organisations launched the Robin Hood Tax campaign on Tuesday (9 Feb), calling for a small tax on speculative banking transactions. The money raised, an estimated £250 billion a year, would be used to tackle poverty and climate change.

The campaigners ran an online poll on its website to find out the opinion of visitors on the campaign, and on Thursday afternoon was hit by 5,000 ‘no’ votes in just 20 minutes.

However, upon investigation, the Robin Hood website found that the votes came from just two computer servers. One of the servers, registered to Goldman Sachs, was responsible for around 1,700 votes. The remaining votes came from a private computer.

Goldman Sachs is reportedly now investigating the issue.

The Robin Hood site has since discounted the anomalous votes and at the time of writing, 3,408 people had voted against the tax, compared to 28,667 votes for.
