She then described how she had gone to the hospital the previous night to identify her sister’s body, saying: “There are some things in life you should never have to do.”
She said: “Yes, this was Jo Cox MP, and she was many things to many people in her too short life.
“But she was my sister, my only sibling, my parents’ first born child, a wife and a mum.
“My parents, my partner and I are quite private people and Jo in true character had fully respected our wish to remain out of the private eye.
“But I could not continue to watch the genuine outpouring of grief, sympathy and love that there has been since this horrendous incident occurred without speaking on behalf of Jo’s family.”
She praised the police and emergency services for the “absolutely outstanding care both Mrs Cox and her family had recieved since the attack.
And she hailed the “brave and courageous” pensioner Bernard Kenny, who stepped between Mrs Cox and her attacker and is now in a stable condition in hospital after being stabbed.
Mrs Leadbeater said the overwhelmingly sympathetic response to Mrs Cox’s death had “genuinely made a difference and helped us through some tough times in the past 48 hours”.
