On 11 February 2023, Esther Ghey’s 16-year-old daughter Brianna was murdered by two fellow schoolchildren. Since that tragedy, Esther has set up Peace in Mind, a campaign to bring mindfulness into schools and help kids channel negative emotions into positive actions. She has taken her brave and passionate campaigning to the House of Commons and called for the limitation of mobile phones in schools, all in the name of preventing future tragedy.
