The Express website breached accuracy rules by wrongly reporting pro-Scottish independence and pro-union activists had “clashed” at a march earlier this year, the UK’s largest press regulator has ruled.

The Independent Press Standards Organisation received 225 complaints about the Express.co.uk article, which said there was a “clash” between the opposing groups in both its headline and standfirst.

The article, which was published in May and removed from the website after complaints were sent in, was headlined: “Scottish nationalists clash with pro-union activists at independence march in Glasgow.”
