Rome, November 13 - Democratic Party (PD) leader Matteo Renzi called on the centre-left group to show unity ahead of elections early next year as he addressed a crunch meeting. "We have the election campaign before us and the effort for unity that is asked of the outside should be practised on the inside first of all by those who lead it (the party)," Renzi said. "This means talking about the country and to the country". Renzi said he would not disavow what has been been achieved by his 2014-2016 administration and the current PD-led government of Premier Paolo Gentiloni. "To those who say that we have to wipe out the past to think about the future, I say that we must strongly lay claim to what we have done," Renzi told a crunch party meeting. "Naturally, there were limits and difficulties, but the country has improved in recent years. "We closed the gap, we got the country going again and we still have lots to do. "Those who say we must disavow what has been done are not aware of where we were three years ago".
