Letta visits former PD secretary Bersani in hospital
Past Democratic Party chief treated for brain hemorrhage17 January, 16:30
Bersani, 62, is in semi-intensive care in the Maggiore hospital in Parma, in north-central Italy.
After his surgery in early January, Bersani's doctors said that there seemed to be no brain damage, adding the patient was "conscious and collaborative".
Bersani failed to lead the centre-left PD to victory in last February's general election despite having a big lead in the polls beforehand after conducting a colourless campaign.
After the vote, he then could not persuade the anti-establishment 5-Star Movement (M5S) to back a government led by him after the election.
Instead, the PD had to settle for a left-right coalition headed by Letta.
Bersani quit as PD chief in April after internal revolts prevented the party from having two of the candidates he had chosen elected as Italian president.
