But Great Ormond Street is holding firm in its wish to end his life and has already rejected an offer of treatment from the Pontiff's own hospital claiming their 'hands are tied'.
Italian Foreign Minister Angelino Alfano says he will now call his counterpart Boris Johnson to urge him to intervene and let the ten-month-old travel to Rome - or America - to prolong his life.
His parents Chris Gard and Connie Yates are at Charlie's bedside today and still believe they can win the battle with his doctors.
Miss Yates said: 'The support from the Pope and the President has given us hope. They are traditional men who believe in the family. They believe in our case and understand why we believe it is right to continue fighting so hard to save Charlie.'
Great Ormond Street is under increasing pressure to change its mind about ending the ten-month-old's life and has already delayed his death twice, MailOnline understands.
