The mother of murdered teenager Brianna Ghey, Esther, is launching her campaign for a ban on mobile phone use during the school day to safeguard pupils and improve behaviour and engagement in class. In February 2023, Brianna, 16, was stabbed to death by two 15-year-olds after being lured to a park in Warrington. In the lead up to the attack, her killers had spent time on the dark web. At the same time, Brianna was also struggling with a phone addiction. #uknews #mobilephones #skynews SUBSCRIBE to our YouTube channel for more videos: http://www.youtube.com/skynews Follow us on Twitter: https://twitter.com/skynews Like us on Facebook: https://www.facebook.com/skynews Follow us on Instagram: https://www.instagram.com/skynews Follow us on TikTok: https://www.tiktok.com/@skynews For more content go to http://news.sky.com and download our apps: Apple https://itunes.apple.com/gb/app/sky-news/id316391924?mt=8 Android https://play.google.com/store/apps/details?id=com.bskyb.skynews.android&hl=en_GB Sky News Daily podcast is available for free here: https://podfollow.com/skynewsdaily/ To enquire about licensing Sky News content, you can find more information here: https://news.sky.com/info/library-sales
