Andrea Orlando, Italy's justice minister, has announced plans to challenge former prime minister Metto Renzi for leadership of the Democratic Party (PD). Orlando's decision is expected to throw a wrench in Renzi's plans to make a political comeback and heightens the chances of a party split.

"But I do not believe either of them have the support to beat Renzi in the primary, so this could actually help him by showing there will be a genuine debate and not just a coronation."
