More in Common
Web site: https://www.moreincommon.org.uk/
More in Common was founded in the aftermath of the tragic murder of Jo Cox MP in 2016. More in Common takes its name from Jo’s maiden speech in Parliament where she said: "We are far more united and have far more in common than that which divides us." Their hope is that through their work, their honour Jo's memory and legacy.
