A desperately ill boy who’s just 16 is in dire need of a stem cell donor to give him a ‘second chance at life’, and now a global search has been launched to help him. Leo Sproson, from Bromsgrove in the Midlands, is at the centre of a worldwide search for a match as he is treated for leukaemia. His parents Jenna and Warren have joined forces with the blood cancer charity DKMS. They face a race against time to find people who could save Leo and others like him with blood cancer.
