Loneliness among youth is rising, with social isolation contributing to poor mental health in both Denmark and the UK. To address this leading Danish and British organisations will share strategies to combat youth loneliness at this conference. Denmark’s political and civil initiatives, and the UK’s appointment of the first minister for loneliness in 2018, offer valuable insights. The conference will be followed by an evening reception. It will be held on Thursday 13 March at The Royal Danish Embassy, London SW1X 9SW.
