Pope Francis has shown slight improvement after 13 days in hospital.  

He's been undergoing treatment for double pneumonia. 

The Vatican's confirmed a CT scan of the pontiff’s chest 'shows a normal evolution' of the inflammation in his lungs. 

Rome Correspondent Jo McKenna told Mike Hosking there could be hope. 

She says the problem he had with his kidneys has receded and he's had no respiratory crisis in the last 48 hours.
